d12ac6c47a ath11k: remove unused tx ring counters
remove unused counter to avoid taking locks inorder to optimize
cpu load.

Using Flamegraph, cpu usage of ath11k_dp_tx() observed to be decreased
from 5.58% to 3.74% with iperf traffic running with 80MHz bandwidth ap
mode.

f1d34a01ed ath11k: avoid WMM param truncation
In conf_tx() mac operation callback, we are truncating the tx
params cw_min and cw_max due to lower data type cast. so modified
the data type of cwmin and cwmax to avoid the trucation issue.

293cb58397 ath11k: optimize RX path latency
This patch drops ath11k_hal_rx_parse_dst_ring_desc(). This function was
creating a huge amount of load, which lead to a signifcant latency delay
when processing data in the RX path.

Pegging the processing on a specific core and running perf --top we get
the following output when running HE80 at a fixed bandwidth of 1gbit.

0f37fbf43c ath11k: update tcl cmd descriptor parameters for STA mode
It is observed that ath11k STA mode UL throughput is low.
This is due to packets delivered to FW from TCL instead of TQM.
TCL AST search fail causes packet delivered to FW, fix this by
properly configuring the TCL address search type and ast_hash.

d5c65159f2 ath11k: driver for Qualcomm IEEE 802.11ax devices
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first
supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k
uses mac80211 and supports AP, Station and Mesh modes.

Even though ath11k has some similar code as with ath10k (especially
the WMI layer) it was concluded to be simpler to have a "clean start"
for ath11k code base and not try to share the code with ath10k. This
makes maintenance easier and avoids major changes in ath10k, which
would have significantly increased the risk of regressions in existing
setups.

Even though the driver is very similar with ath10k but there are major
differences as well. The datapath is completely different. ath11k
supports multiple MACs, called "soc" in the firmware interface. And
there's only one WMI interface to support.

Currently ath11k supports only IEEE 802.11ac mode, but patches for
802.11ax are available and they will be submitted after ath11k is
accepted to upstream.

The firmware images are available from ath11k-firmware repository but
they will be also submitted to linux-firmware:

https://github.com/kvalo/ath11k-firmware

This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.

The driver has had multiple authors who are listed in alphabetical
order below.

ea0c3e2a47 ath10k: fix RX of frames with broken FCS in monitor mode
So far, frames were forwarded regardless of the FCS correctness leading
to userspace applications listening on the monitor mode interface to
receive potentially broken frames, even with the "fcsfail" flag unset.

By default, with the "fcsfail" flag of a monitor mode interface
unset, frames with FCS errors should be dropped. With this patch, the
fcsfail flag is taken into account correctly.

319c2b7104 ath10k: Handle "invalid" BDFs for msm8998 devices
When the BDF download QMI message has the end field set to 1, it signals
the end of the transfer, and triggers the firmware to do a CRC check.  The
BDFs for msm8998 devices fail this check, yet the firmware is happy to
still use the BDF.  It appears that this error is not caught by the
downstream drive by concidence, therefore there are production devices
in the field where this issue needs to be handled otherwise we cannot
support wifi on them.  So, attempt to detect this scenario as best we can
and treat it as non-fatal.

67654b26c9 ath10k: add workqueue for RX path of sdio
For RX, it has two parts, one is to read data from sdio, another
is to indicate the packets to upper stack. Recently it has only
one thread to do all RX things, it results that it is sequential
for RX and low throughout, change RX to parallel for the two parts
will increase throughout.

This patch move the indication to a workqueue, it results in
significant performance improvement on RX path.

Udp rx throughout is 200Mbps without this patch, and it arrives
400Mbps with this patch.

224776520e ath10k: change max RX bundle size from 8 to 32 for sdio
The max bundle size support by firmware is 32, change it from 8 to 32
will help performance. This results in significant performance
improvement on RX path.

The real max rx bundle is decided in ath10k_htc_wait_target(),
it is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and the value reported
from firmware. So this change shouldn't cause any regressions with other
hardware supported by ath10k.

8d985555dd ath10k: enable RX bundle receive for sdio
The existing implementation of initiating multiple sdio transfers for
receive bundling is slowing down the receive speed. Combining the
transfers using a bundle method would be ideal.

The transmission utilization ratio for sdio bus for small packet is
slow, because the space and time cost for sdio bus is same for large
length packet and small length packet. So the speed of data for large
length packet is higher than small length.

Test result of different length of data:
data packet(byte)   cost time(us)   calculated rate(Mbps)

cpuidle's miss predictions make it worse. In the worst case,
resume time can be three times longer than the average on sdio.

It is because 8192cu doesn't implement usb_cmd_send_packet(), and this
patch just frees the skb within the function to resolve memleak problem
by now. Since 8192cu doesn't turn on fwctrl_lps that needs to download
command packet for firmware via the function, applying this patch doesn't
affect driver behavior.

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.

As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

bf9840ccf8 rtw88: raise LPS threshold to 50, for less power consumption
The LPS threshold was set to 2, means driver will leave LPS
mode if there is more than 2 frames TX/RX for every 2 seconds.
This makes driver enter/leave LPS frequently even if we just
"ping -i1" to the others.

Apparently we do not want to leave LPS mode if there is only
some background traffics or web surfing. By experiment, set
this to 50 is a more reasonable value to lower the over all
power consumption.
