In QCN9074, station dump signal values display default value which
is -95 dbm, since there is firmware header change for HAL_RX_MPDU_START
between QCN9074 and IPQ8074 which cause wrong peer_id fetch from msdu.
Fix this by updating hal_rx_mpdu_info with corresponding QCN9074 tlv

ath11k: Fix unexpected return buffer manager error for QCA6390

ath11k: Fix unexpected return buffer manager error for QCA6390

We are seeing below error on QCA6390:
...
[70211.671189] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22

[70213.092941] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22
...

The reason is that, with commit 734223d78428 ("ath11k: change return
buffer manager for QCA6390"), ath11k expects the return buffer manager
(RBM) field of descriptor configured as HAL_RX_BUF_RBM_SW1_BM when
parsing error frames from WBM2SW3_RELEASE ring. This is a wrong change
cause the RBM field is set as HAL_RX_BUF_RBM_SW3_BM.

The same issue also applies to REO2TCL ring though we have not got any
error reported.

Fix it by changing RBM from HAL_RX_BUF_RBM_SW1_BM to HAL_RX_BUF_RBM_SW3_BM
for these two rings.

After that, "iw wlan0 station dump" show the correct tx bit rate such

then report them to mac80211.

WMI_REQUEST_STATS_CMDID is only sent when CONFIG_ATH11K_DEBUGFS is set,
it is only called by ath11k_mac_op_sta_statistics(). It does not effect
performance and power consumption. Because after STATION connected to

In preparation for FORTIFY_SOURCE performing compile-time and run-time

neighboring fields.

Use memset_startat() so memset() doesn't get confused about writing
beyond the destination member that is intended to be the starting point
of zeroing through the end of the struct. Additionally split up a later
field-spanning memset() so that memset() can reason about the size.

Now some of the HAL register macros access ab variable in a hidden way, make ab
variable visible in the macro by adding it as an argument.

This is done in a separate patch to keep the patches simple. No functional changes.

ath11k: hal: create hw_srng_config dynamically

On QCA6390 reg_start and reg_size values are different from IPQ8074 so we need
to change the values runtime. As we can't modify a static const variable
hw_srng_config directly, instead use it as a template, copy it and modify the
copy with correct values.

ath11k: Configure hash based reo destination ring selection

Current implementation of pdev based reo destination ring
selection is replaced by hash based ring selection so as to
ensure all the available rings are utilized for better performance.

The 4 reo destination rings are selected by the HW based on the
hash value computed from the received packet based on the 5 tuple
{ip src/ip dst/src port/dst port/protocol}. Out of the 32 hash values
used by the hw, the driver assigns 8 values per reo destination ring
to each of the 4 reo destination rings.

ath11k: enable PN offload

Enabling PN checking in the hardware; hardware checks
the PN of the received packets and reports the errors
to the host for further handling; default action is to
drop such packets. TSC (TKIP sequence counter)
validation is also offloaded.

Hardware validates PN/TSC only for unicast packets;
for group addressed packets, PN validation is done
in mac80211.

PN errors are reported to the driver via WBM RX release
ring and can be dumped by using the following command.

"cat /sys/kernel/debug/ath11k/soc_rx_stats | grep -i pn"

Sample Output:
PN check fail: 210

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.

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.
