Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

pass that through to the driver's sta_rc_update() method. The

A mac_id as an instance in firmware has to be assigned for each station
including AP and connected stations. Firmware will use the mac_id to
control TX rate and do statistics.
Assignment rule is to assign mac_id to each vif when adding vif.
For station mode, sta->mac_id will reuse vif->mac_id. For AP mode,
dynamically allocate an sta->mac_id to a station, and vif->mac_id is
used to send broadcast/multicast packets which are not belong to
a station. For example,
vif->mac_id sta->mac_id
vif0 (STA mode) 0 0
vif1 (AP mode) 1 2...
By the way, remove unused RTW_BC_MC_MACID, which was planed to send
broadcast/multicast packets on fixed mac_id.
Tested-on RTL8822CE with STA + AP SCC mode.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the

In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through
nl80211_tx_control_port() and triggers wake_tx_queue() in the driver.
Then, it sends nl80211_new_key() to configure a new key in mac80211.
However, in wake_tx_queue(), a workqueue is used to process the tx packet,
which might cause the driver to process the EAPOL packet later than
nl80211_new_key(). As a result, the EAPOL 4/4 packet is dropped by mac80211
due to the rekey configuration being finished. The EAPOL packets belongs to
VO packets that need high priority. Therefore, we process VO packets
directly without workqueue to ensure that packets can process immediately.
VO is normally used by voice application that is low traffic load and low
latency, that doesn't affect user experience.

This driver relies on IEEE80211_CONF_PS of hw->conf.flags to turn off PS or
turn on dynamic PS controlled by driver and firmware. Though this would be

the commit 28977e790b ("wifi: mac80211: skip powersave recalc if driver SUPPORTS_DYNAMIC_PS")
is introduced by kernel 5.20 to skip to recalculate IEEE80211_CONF_PS
of hw->conf.flags if driver sets SUPPORTS_DYNAMIC_PS.
Correct this by doing recalculation while BSS_CHANGED_PS is changed and
interface is added or removed. It is allowed to enter PS only if single
one station vif is working. Without this fix, driver doesn't enter PS
anymore that causes higher power consumption.

misconfigured after scan. Download beacon just before scan starts to

To support stations in power saving mode, AP should notify stations
that there are frames buffered at the AP via TIM during beacons.
Driver used to transmit identical beacons that were downloaded to
hardware during the initiation phase. This beacon will become
obsolete over time.
If the beacon does not contain sufficient information, station would
not be able to percept that there is data to receive. Hence it won't
wake up and start the PS-poll procedure, this could lead to timeout
and/or lost data segments. In order to resolve this issue, driver will
now download beacon to hardware whenever the content is updated.
Enable hardware to update dtim_count for more efficiency, this reduces
the overhead of downloading beacon at every beacon interval since most
of the time only the dtim_count needs to be updated.
Change queue mapping for broadcast/multicast frames to high queue, so
these frames can be prioritized and sent when dtim_count is zero.

Register cfg80211_sar_capa with type NL80211_SAR_TYPE_POWER and four
frequency ranges for configurations in unit of 0.25 dBm. And handle
callback set_sar_specs.
Originally, TX power has three main parameters, i.e. power base,
power by rate, and power limit. The formula can be simply considered
as TX power = power base + min(power by rate, power limit). With the
support of SAR which can be treated as another power limit, there is
one more parameter for TX power. And the formula will evolve into
TX power = power base + min(power by rate, power limit, power sar).
Besides, debugfs tx_pwr_tbl is also refined to show SAR information.
The following is an example for the difference.
Before supporting SAR,
-----------------------------------
...
path rate pwr base (byr lmt ) rem
A CCK_1M 66(0x42) 78 -12 ( 12 -12) 0
A CCK_2M 66(0x42) 78 -12 ( 8 -12) 0

After supporting SAR and making some configurations,

...

A CCK_1M 62(0x3e) 78 -16 ( 12 -12 -16) 0

Declare this function allows us to use customized scanning policy.
By doing so we can be more time efficient on each scan. In order to
make existing coex mechanism work as usual, firmware notifies driver
on each channel switch event, then decide antenna ownership based on
the current channel/band. Do note that this new mechanism affects
throughput more than the sw_scan we used to have, but the overall
average throughput is not affected since each scan take less time.
Since the firmware size is limited, we only support probe requests
with custom IEs length under 128 bytes for now, if any user space
tools requires more than that, we'll introduce related changes
afterwards. For backward compatibility, we fallback to sw_scan when
using older firmware that does not support this feature.

====================
Lots of changes:
* aggregation handling improvements for some drivers
* hidden AP discovery on 6 GHz and other HE 6 GHz
improvements
* minstrel improvements for no-ack frames
* deferred rate control for TXQs to improve reaction
times
* virtual time-based airtime scheduler
* along with various little cleanups/fixups

We have mgd_prepare_tx(), but sometimes drivers may want/need
to take action when the exchange finishes, whether successfully
or not.
Add a notification to the driver on completion, i.e. call the
new method mgd_complete_tx().
To unify the two scenarios, and to add more information, make
both of them take a struct that has the duration (prepare only),
subtype (both) and success (complete only).

It is found that driver scan could be affected by dynamic mechanism
of firmware, so we notify firmware to stop it in the scan period.
Another, firmware will detect the background noise and report to
driver for further use.

Adding this supports beacon filter and CQM.
Let firmware perform connection quality monitor and beacon processing.
This make host CPU wakeup less under power save mode.
To make mechanisms work as usual, fw will notify driver events such as
signal change and beacon loss.
This feature needs firmware 9.9.8 or newer to support it, and driver is
compatible with older firmware.

Though mac queue flushing has been supported, sometimes data may be waiting
on interface from host to chip. If it occurs, there may still be data that
flows into mac just after we do flush. To avoid that, we add the hci part
of flushing.

Replace tasklet so we can do tx scheduling in parallel. Since throughput
is delay-sensitive in most cases, we allocate a dedicated, high priority
wq for our needs.

Add considering for different WLAN beacon interval in coexistence
mechanism.
Because the WLAN beacon period may be not 100 ms, so it's necessary
to consider any beacon period and set timer according to the interval.
