1554ed2088 iwlwifi: pcie: use shadow registers for updating write pointer
The RX queues have a shadow register for the write pointer
that enables updates without grabbing NIC access. Use them
instead of the periphery registers because accessing those
is much more expensive.

cf961e1662 iwlwifi: mvm: support dqa-mode agg on non-shared queue
In non-shared queues, DQA requires re-configuring existing
queues to become aggregated rather than allocating a new
one. It also requires "un-aggregating" an existing queue
when aggregations are turned off.

Support this requirement for non-shared queues.

b7a08b284d iwlwifi: pcie: extend device reset delay
Newer hardware generations will take longer to be accessible again
after reset, so we need to wait longer before continuing any flow
that did a reset.

Rather than make the wait time configurable, simply extend it for
all.

Since all of these code paths can sleep, use usleep_range() rather
than mdelay().

39654cb3a6 iwlwifi: don't access a nonexistent register upon assert
The commit below added code to dump the content of FIFOs
that are present only on dual CPU products (8000 and up).
This broke 7265D whose firmware does advertise
IWL_UCODE_TLV_CAPA_EXTEND_SHARED_MEM_CFG but doesn't have 2
CPUs. The current code does check the length of the FIFO
before dumping them (and the nonexistent FIFO has a 0
length), but we still accessed a register to set the FIFO
number and that made the DMA unhappy.

The impact was a much longer recovery upon firmware assert.

74dd17648c iwlwifi: mvm: loosen nssn comparison to reorder buffer head
Up till now, the reorder buffer uses standard spec based comparison
when comparing the buffer status to NSSN. This indeed works for the
regular case, since we shouldn't cross the 2048 boundary without
getting a frame release notification.
However, this is problematic due to packet filtering that may be
performed by the FW while we are in d0i3. Theoretically we may
filter over 2048 packets, and then the check of the NSSN will get
incorrect.
Change the comparison to always trust nssn unless it is 64 or less
frames behind the head - which might happen due to a timeout.
This new comparison is to be used only when comparing reorder buffer
head with nssn, and not when comparing the packet SN to nssn or
reorder buffer head.
Put this in a separate commit as the logic is a bit tricky and
stands for its own commit message.

16c45822a8 iwlwifi: mvm: don't allow negative reference count
Currently code allows mvm reference to become negative and
only warns in case mvm reference is released while reference
counting is 0.
However, we better prevent this from happening at all since
iwl_mvm_unref() may race against iwl_mvm_unref_all_except()
which is called on restart.
As a result we might get the same reference unreferenced twice
ending with a negative value:
An example for an easily reproduced log:
    [ 2689.909166] iwl_mvm_ref Take mvm reference - type 8
    [ 2690.732716] iwl_mvm_unref_all_except Cleanup: remove mvm ref type 8 (1)
    [ 2690.849708] iwl_mvm_unref Leave mvm reference - type 8
    [ 2690.849721] WARNING: ... iwl_mvm_unref+0xb0/0xc0 [iwlmvm]()

If there will be yet another another restart iwl_mvm_unref_all_except
will run from 0 up to ref count, and since it is unsigned, we will throw
the transport ref count completely out of balance:
    iwl_mvm_unref_all_except[I] -- Cleanup: remove mvm ref type 8 (255)
    iwl_trans_slv_unref[I] -- rpm counter: 0
    iwl_trans_slv_unref[I] -- rpm counter: -1
    iwl_trans_slv_unref[I] -- rpm counter: -2
 ...
    iwl_trans_slv_unref[I] -- rpm counter: -253
    iwl_trans_slv_unref[I] -- rpm counter: -254

As there is no valid scenario where we can get to a negative
reference count - prevent it from happening.

0690405fef iwlwifi: mvm: add reorder timeout per frame
Add a timer in order to release expired frames from the
reorder buffer.
This is needed since some APs do not retransmit frames
to fill in the reorder holes and in TCP it results with
a complete stall of traffic.

This has a few side effects on the general design:

The nssn may not reflect the the head of the reorder buffer.
This situation is valid, and packets with SN lower than the
reorder buffer head will be dropped.

Another side effect is that since the reorder timer might expire
we need to lock the reorder buffer.
This however is fine since the locking is only inside a
single reorder buffer between RX path and reorder timeout and
there is no outside contention.

b915c10174 iwlwifi: mvm: add reorder buffer per queue
Next hardware will direct packets to core based on the TCP/UDP
streams.
This logic can create holes in reorder buffer since packets that
belong to other stream were directed to a different core.
However, those are valid holes and the packets can be indicated
in L3 order.

The hardware will utilize a mechanism of informing the driver of
the normalized ssn and the driver shall release all packets that
SN is lower than the nssn.
This enables managing the reorder across the queues without sharing
any data between them.

The reorder buffer is allocated and released directly in the RX path
in order to avoid various races between control path and rx path.
The code utilizes the internal messaging to notify rx queues of when
to delete the reorder buffer.

fa7937e3d5 ath10k: update bss channel survey information
During hw scan, firmware sends two channel information events (pre-
complete, complete) to host for each channel change. The snap shot of cycle
counters (rx_clear and total) between these two events are given for
survey dump. In order to get latest survey statistics of all channels, a
scan request has to be issued. In general, an AP DUT is brought up, it
won't leave BSS channel except few cases like overlapping bss or radar
detection. So survey statistics of bss channel is always referring to
older data that are collected before starting AP (either ACS/OBSS scan).

To collect latest survey information from target, firmware provides WMI
interface to read cycle counters from hardware. For each survey dump
request, BSS channel cycle counters are read and cleared in hardware.
This makes sure that behavior is in align with ath9k survey report.
So survey dump always gives snap shot of cycle counters b/w two survey
requests.

94ee3f19b1 ath10k: remove VHT capabilities from 2.4GHz
According to the spec, VHT doesn't exist in 2.4GHz.

There are vendor extensions to allow a subset of VHT to work
(notably 256-QAM), but since mac80211 doesn't support those
advertising VHT capability on 2.4GHz leads to the behaviour
of reporting VHT capabilities but not being able to use any
of them due to mac80211's code requiring 80 MHz support.

Remove the VHT capabilities from 2.4GHz for now. If mac80211
gets extended to use the (likely Broadcom) vendor IEs for it
and handles the lack of 80 MHz support, it can be added back.

5c08b0f502 iwlwifi: mvm: don't override the rate with the AMSDU len
The TSO code creates A-MSDUs from a single large send. Each
A-MSDU is an skb and skb->len doesn't include the number of
bytes which need to be added for the headers being added
(subframe header, TCP header, IP header, SNAP, padding).

To be able to set the right value in the Tx command, we
put the number of bytes added by those headers in
driver_data in iwl_mvm_tx_tso and use this value in
iwl_mvm_set_tx_cmd.

The problem by setting this value in driver_data is that
it overrides the ieee80211_tx_info. The bug manifested
itself when we send P2P related frames in CCK since the
rate in ieee80211_tx_info is zero-ed. This of course is
a violation of the P2P specification.

To fix this, copy the original ieee80211_tx_info to the
stack and pass it to the functions which need it.
Assign the number of bytes added by the headers to the
driver_data inside the skb itself.

8527f68849 wcn36xx: Set SMD timeout to 10 seconds
After booting the wireless subsystem and uploading the NV blob to the
WCNSS_CTRL service the remote continues to do things and will not start
servicing wlan-requests for another 2-5 seconds (measured).

The downstream code does not have any special handling for this case,
but has a timeout of 10 seconds for the communication layer. By
extending the wcn36xx timeout to match this we follows the same flow for
the boot procedure and can successfully configure WiFi as wlan0 is
registered.

349214c1e7 wil6210: prevent deep sleep of 60G device in critical paths
In idle times 60G device can enter deep sleep and turn off
its XTAL clock.
Host access triggers the device power-up flow which will hold
the AHB during XTAL stabilization until device switches from
slow-clock to XTAL clock.
This behavior can stall the PCIe bus for some arbitrary period
of time.
In order to prevent this stall, host can vote for High Latency
Access Policy (HALP) before reading from PCIe bus.
This vote will wakeup the device from deep sleep and prevent
deep sleep until unvote is done.

P2P search can only run on the social channel (channel 2).
When issuing a scan request on the P2P_DEVICE interface,
driver ignored the channels argument and always performed a P2P

Fix this by checking the channels argument, if it is
not specified (meaning full scan) or if a non-social channel

f0d8f38cd9 iwlwifi: fix fw version reading for DVM devices
In commit 97f95c93c8 ("iwlwifi: remove support for fw older than
-16.ucode") we accidentally changed the fw version reading code for
DVM devices.  The code intended to remove the old fw version API,
because all MVM firmwares version 16 and above that we support don't
use it anymore.  But DVM devices still use the old FW API.

Fix that by bringing the code back in.

91c3eeba45 wcn36xx: Pad TIM PVM if needed
The wcn36xx FW expects a fixed size TIM PVM in the beacon template. If
supplied with a shorter than expected PVM it will overwrite the IE
following the TIM.

Squashed with fix from Jason Mobarak <jam@cozybit.com>:
Patch "wcn36xx: Pad TIM PVM if needed" has caused a regression in mesh
beaconing.  The field tim_off is always 0 for mesh mode, and thus
pvm_len (referring to the TIM length field) and pad are both incorrectly
calculated.  Thus, msg_body.beacon_length is incorrectly calculated for
mesh mode. Fix this.

7ebf721d0d ath10k: refactor firmware images to struct ath10k_fw_components
To make it easier to share ath10k_core_fetch_board_data_api_n() with testmode.c
refactor all firmware components to struct ath10k_fw_components. This structure
will hold firmware related files, for example firmware-N.bin and board-N.bin.

For firmware-N.bin create a new struct ath10k_fw_file which contains the actual
firmware image as well as the parsed data from the image.

Modify ath10k_core_start() to take struct ath10k_fw_components() as an argument
which makes it possible in following patches to drop some ugly hacks from
testmode.c.

71f5137bf0 ath9k: interpret requested txpower in EIRP domain
Tx power limitations at upper layers are interpreted in
the EIRP domain. When the user requests a given maximum
txpower, e.g. with: 'iw phy0 set txpower fixed 1500',
he expects the EIRP to be at or below 15dBm.

In ath9k_hw_apply_txpower(), the interpretation is
different: the antenna-gain is capped against the
current txpower limit in the regulatory, but not
against the user set value. It ensures that the
resulting EIRP is below the limit defined by the
active countrycode, but not below the value the
user requested.

In a scenario like e.g.
 a) antenna_gain=6
 b) countrycode limits to eirp=18
 c) user set txpower=15
this will cause a setting for AR_PHY_POWER_TX_RATE
regs resulting in an EIRP > 15.

This patch ensures that antenna-gain is considered
whenever the txpower limit is adjusted and with that
the user set limits are kept.

7e247a9e88 ath10k: add dynamic tx mode switch config support for qca4019
push-pull mode needs certain amount the host driver involvement for
managing queues in the host memory and packet delivery to firmware.
qca4019 wifi firmware has an option to stay in push mode for less
number of active traffic flow and then switch to push-pull mode when
the active traffic flow goes beyond the certain limit.

The advantage of staying in push mode for less active traffic is, the
host cpu consumption is reduced. qca4019 firmware supports this
flexibility of the mode switch. It takes the host driver interest
(LOW_PERF/HIGH_PERF) via WMI_EXT_RESOURCE_CFG_CMDID,

 LOW_PERF  - fw would stay in push mode and switch to push-pull
               based on demand.
 HIGH_PERF - fw would stay in push-pull mode from the boot.

To make this configuration generic, new WMI services
WMI_SERVICE_TX_MODE_PUSH_ONLY, WMI_SERVICE_TX_MODE_PUSH_PULL,
WMI_SERVICE_TX_MODE_DYNAMIC are introduced to take dynamic tx mode
switch support availability in firmware.
Based on WMI_SERVICE_TX_MODE_DYNAMIC, LOW_PERF or HIGHT_PERF is
configured to the firmware.

Upon firmware assert, restart work will be triggered so that mac80211

work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info
for operating channel. During reconfigure, since mac80211 already has
valid channel context for given radio, channel context iteration return
num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning

c70ca8cb9a mwifiex: factor out mwifiex_cancel_pending_scan_cmd
Releasing the scan_pending lock in mwifiex_check_next_scan_command
introduces a short window where pending scan commands can be removed
or added before removing them all in mwifiex_cancel_pending_scan_cmd.
I think this is safe, since the worst thing to happen is that a
pending scan cmd is removed by the command handler. Adding new scan
commands is not possible while one is pending, see scan_processing flag.
Since all commands are removed from the queue anyway, we don't care if
some commands are removed by a different code path earlier, the final
state remains the same.
I assume, that the critical section needed for the check has been
extended over clearing the pending scan queue out of convenience. The
lock was already held and releasing it and grab it again was just
more work. It doesn't seem to be necessary because of concurrency.

Move event handling out of brcmf_netif_rx() avoiding the need
to pass a flag. This flag is only ever true for USB hosts as
other interface use separate brcmf_rx_event() function.

c56caa9db8 brcmfmac: screening firmware event packet
Firmware uses asynchronized events as a communication method to the
host. The event packets are marked as ETH_P_LINK_CTL protocol type. For
SDIO and PCIe bus, this kind of packets are delivered through virtual
event channel not data channel. This patch adds a screening logic to
make sure the event handler only processes the events coming from the
correct channel.

When p2p connection setup is performed without having ever done an

to abort scanning is taken from escan struct while it was never

abort should still be performed and all scan related commands are

f742aaf36e iwlwifi: mvm: fix accessing Null pointer during fw dump collection
The firwmare file can come with data that is relevant for paging. This
data is availablet to the firmware upon request, but it stored in the
host's memory. During the firmware init flow, the driver configures the
firmware so that the firwmare knows where is the data.
When paging is used, the variable paging_mem_size is the number of bytes
that are available through paging. This variable is not zeror-ed if the
driver fails to configure the paging in the firmware, but the memory is
freed which is inconsistent.
This inconsistency led to a NULL pointer dereference in the code that
collects the debug data.

Fix this by zero-ing the paging_mem_size variable and NULLify the
relevant pointers, so that the code that collects the debug data will
know that the paging data is not available.

84d17a2a5a iwl4965: Fix more memory leaks in __il4965_up()
In some of the non-success return paths, the memory allocated by
iwl4965_sta_alloc_lq() in iwl4965_alloc_bcast_station() is not freed.

In particular:
 - if the card isn't ready after il4965_prepare_card_hw()
 - if the card is hardware-rfkilled

In the hardware rfkilled path, the driver enables the rfkill
interrupt. When the card is unrfkilled and this interrupt is raised
we end up calling il4965_bg_restart() which calls __il4965_up() which
calls iwl4965_alloc_bcast_station() again.

fe9b47944e iwl4965: Fix a null pointer dereference in il_tx_queue_free and il_cmd_queue_free
If "txq->cmd = kzalloc(...)" in il_tx_queue_init fails,
"kfree(txq->cmd[i])" in il_tx_queue_free and il_cmd_queue_free
in iwl4965_hw_txq_ctx_free will causes a null pointer dereference,
because txq->cmd is NULL at that time.

This patch fixes this problem by adding a if-check before kfree.
To avoid double free in il_tx_queue_free and il_cmd_queue_free
caused by the fixing, txq->meta and txq->cmd in error handling code
of il_tx_queue_init are assigned null values.
Otherwise, a double free will occur.

This patch has been tested in real device, and it actually fixes the bug.

c18d8f5095 rtlwifi: rtl8723be: Add antenna select module parameter
A number of new laptops have been delivered with only a single antenna.
In principle, this is OK; however, a problem arises when the on-board
EEPROM is programmed to use the other antenna connection. The option
of opening the computer and moving the connector is not always possible
as it will void the warranty in some cases. In addition, this solution
breaks the Windows driver when the box dual boots Linux and Windows.

A fix involving a new module parameter has been developed.  This commit
adds the new parameter and implements the changes needed for the driver.

128abd0913 ath10k: reuse copy engine 5 (htt rx) descriptors
Whenever htt rx indication i.e target to host messages are received
on rx copy engine (CE5), the message will be freed after processing
the response. Then CE 5 will be refilled with new descriptors at
post rx processing. This memory alloc and free operations can be avoided
by reusing the same descriptors.

During CE pipe allocation, full ring is not initialized i.e n-1 entries
are filled up. So for CE 5 full ring should be filled up to reuse
descriptors. Moreover CE 5 write index will be updated in single shot
instead of incremental access. This could avoid multiple pci_write and
ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019
platform.

24afba7690 iwlwifi: mvm: support bss dynamic alloc/dealloc of queues
"DQA" is shorthand for "dynamic queue allocation". This
enables on-demand allocation of queues per RA/TID rather than
statically allocating per vif, thus allowing a potential
benefit of various factors.

Please refer to the DOC section this patch adds to sta.h to
see a more in-depth explanation of this feature.

There are many things to take into consideration when working
in DQA mode, and this patch is only one in a series. Note that
default operation mode is non-DQA mode, unless the FW
indicates that it supports DQA mode.

This patch enables support of DQA for a station connected to
an AP, and works in a non-aggregated mode.

When a frame for an unused RA/TID arrives at the driver, it
isn't TXed immediately, but deferred first until a suitable
queue is first allocated for it, and then TXed by a worker
that both allocates the queues and TXes deferred traffic.

When a STA is removed, its queues goes back into the queue
pools for reuse as needed.

c772a3d3fa iwlwifi: pcie: do not pad QoS AMSDU
We insert padding if the MAC header's size is not a multiple of 4
to ensure that the SNAP header is DWORD aligned. When we do so, we
let the firmware know by setting a bit in Tx command
(TX_CMD_FLG_MH_PAD) which will instruct the firmware to drop those
2 bytes before sending the frame.
However, this is not needed for AMSDU as the sub frame header (14B)
complements the MAC header (26B) so that the SNAP header is DWORD
aligned without adding any pad.

Until 9000, the firmware didn't check the TX_CMD_FLG_MH_PAD bit
but rather checked the length of the MAC header itself and
assumed the entity that enqueued the frame (driver or internal
firmware code) added the pad.
Since the driver inserted the pad even for AMSDU this logic applied.
Note that the padding is a DMA optimization but it's not strictly
needed, so we could pad even if it was not needed.

However, the CSUM hardware introduced for the 9000 devices requires
to not pad AMSDU as it is not needed, and will fail if such a pad
exists.
Due to older FW not checking the padding bit but checking the mac
header size itself - we cannot do this adjustments for older
generations.
Do not align the size if it is an AMSDU and HW checksum is enabled -
which will only happen on 9000 devices and on.

On resume the driver calls only iwl_pcie_reset_ict() without calling

This mostly works since iwl_pcie_reset_ict is calling to
iwl_enable_interrupts, but it doesn't work when there is no ict_table

The result is that driver tries to resume but fails since it doesn't

LQM stands for Link Quality Measurement. The firmware
will collect a defined set of statitics (see the
notification for details) that allow to know how busy
the medium is. The driver issues a request to the firmware
that includes the duration of the measurement (the firmware
needs to be on channel for that amount of time) and the
timeout (in case the firmware has a lot of offchannel
activities). If the timeout elapses, the firmware will
send partial results which are still valuable.
In case of disassociation / channel switch and alike, the
driver is in charge of stopping the measurements and the
firmware will reply with partial results.

The user space API for now is debugfs only and will be
implmemented in an upcoming patch.

3d9195ea19 ath10k: incorporate qca4019 cal data download sequence
qca4019 calibration data is stored in the host memory and it's mandatory
to download it even before reading board id and chip id from the target.
Also, there is a need to execute otp (download and run) twice, one after
cal data download and another one after board data download.

Existing cal data file name 'cal-<bus>-<id>.bin' and device tree entry
'qcom,ath10k-calibration-data' used in ath10k has assumption that it
carries other data (like board data) also along with the calibration data.
But, qca4019 cal data contains pure calibration data (doesn't include
any other info). So, using existing same cal file name and DT entry
in qca4019 case would alter the purpose of it. To avoid this, new cal
file name 'pre-cal-<bus>-<id>.bin' and new device tree entry name
'qcom,ath10k-pre-calibration-data are introduced.

Overall qca4019's firmware download sequence would look like,

   1) Download cal data (either from a file or device tree entry)
      at the address specified by target in the host interest area
      member "hi_board_data".

   2) Download otp and run with 0x10 (PARAM_GET_EEPROM_BOARD_ID)
      as a argument.

      At this point, otp will take back up of downloaded cal data
      content in another location in the target and return valid
      board id and chip id to the host.

   3) Download board data at the address specified by target
      in host interest area member "hi_board_data".

   4) Download otp and run with 0x10000 (PARAM_FLASH_SECTION_ALL) as
      a argument.

      Now otp will apply cal data content from it's backup on top
      of board data download in step 3 and prepare final data base.

   5) Download code swap and athwlan binary content.

Above sequences are implemented (step 1 to step 4) in the name of
pre calibration configuration.

hard coded file pointer (ar->cal_file) and device tree entry

There is a need to use those two functions in qca4019 calibration
download sequence with different file pointer and device tree entry name.
Modify those two functions to take cal data location as an argument.
So that it can serve the purpose for other file pointer and device
tree entry.

This is just preparation before adding actual qca4019 calibration

c94d7996db iwlwifi: mvm: Decrease size of the paging download buffer
Currently the driver has 2 buffers for paging:
1. paging db - this contains all of the pages that were in the FW
image, that the driver stores for the FW. This is allocated for each
block separately (not contiguous).
2. download buffer - we need to provide this empty buffer for the
iwl_sdio_load_fw_chunk function to copy the requested pages to the shared
memory. This is one big buffer of contiguous memory whose size is the
size of all the blocks that the fw paging section can contain.

This download buffer size is too big, and causes the allocation to fail
sometimes. Since the driver allocates memory for each block separately,
it is not possible for the FW to request all of the pages in one request
(the FW gives an address and size, so blocks need to be contiguous for
this to happen), therefore the FW is limited to request only one block.

Decrease the size of the paging download buffer to be the size of a
paging block.

bf031bc4d6 ath10k: advertise force AP scan feature
Results obtained from scan can be used for spectrum management by
doing something like building information of preferred channel
lists and sharing them with stations around. It is to be noted
that traffic to the connected stations would be affected during
the scan.

cac085524c ath10k: move mgmt descriptor limit handle under mgmt_tx
Frames that are transmitted via MGMT_TX are using reserved descriptor
slots in firmware. This limitation is for the htt_mgmt_tx path itself,
not for mgmt frames per se. In 16 MBSSID scenario, these reserved slots
will be easy exhausted due to frequent probe responses. So for 10.4
based solutions, probe responses are limited by a threshold (24).

management tx path is separate for all except tlv based solutions. Since
tlv solutions (qca6174 & qca9377) do not support 16 AP interfaces, it is
safe to move management descriptor limitation check under mgmt_tx
function. Though CPU improvement is negligible, unlikely conditions or
never hit conditions in hot path can be avoided on data transmission.

2ce9b25cef ath10k: handle channel change htt event
Whenever firmware is configuring operating channel during scan or
home channel, channel change event will be indicated to host. In some
cases (device probe/ last vdev down), target will be configured to
default channel whereas host is unaware of target's operating channel.
This leads to packet drop due to unknown channel and kernel log will be
filled up with "no channel configured; ignoring frame(s)!". Fix that
by handling HTT_T2H_MSG_TYPE_CHAN_CHANGE event.

362210e0df ath9k: fix misleading indentation
A cleanup patch in linux-3.18 moved around some code in the ath9k
driver and left some code to be indented in a misleading way,
made worse by the addition of some new code for p2p mode, as
discovered by a new gcc-6 warning:

drivers/net/wireless/ath/ath9k/init.c: In function 'ath9k_set_hw_capab':
drivers/net/wireless/ath/ath9k/init.c:851:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
    hw->wiphy->iface_combinations = if_comb;
    ^~
drivers/net/wireless/ath/ath9k/init.c:847:3: note: ...this 'if' clause, but it is not
   if (ath9k_is_chanctx_enabled())
   ^~

The code is in fact correct, but the indentation is not, so I'm
reformatting it as it should have been after the original cleanup.

83d6f1f15f ath9k: fix buffer overrun for ar9287
Code that was added back in 2.6.38 has an obvious overflow
when accessing a static array, and at the time it was added
only a code comment was put in front of it as a reminder
to have it reviewed properly.

This has not happened, but gcc-6 now points to the specific
overflow:

drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs':
drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds]
     maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4];
                   ~~~~~~~~~~~~~~~~~~~~~~~~~^~~

It turns out that the correct array length exists in the local
'intercepts' variable of this function, so we can just use that
instead of hardcoding '4', so this patch changes all three
instances to use that variable. The other two instances were
already correct, but it's more consistent this way.
