When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath11k will check the capability, and if it is enabled then
ath11k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath11k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware and also notifies cfg80211.
This only enable rfkill feature for QCA6390, rfkill_pin is all initialized to 0
for other chips in ath11k_hw_params.

HTT_T2H_MSG_TYPE_PPDU_STATS_IND is a message which include the ppdu
info, currently it is not report from firmware for ath11k, then the
tx bitrate of "iw wlan0 station dump" always show an invalid value
"tx bitrate: 6.0 MBit/s".
To address the issue, this is to parse the info of tx complete report
from firmware and indicate the tx rate to mac80211.
After that, "iw wlan0 station dump" show the correct tx bit rate such
as:
tx bitrate: 78.0 MBit/s MCS 12

Whenever the MAC detects a color collision, or any of
its associated stations detects one, the firmware will
send out an event. Add the code to parse and handle
this event and pass the data up to mac80211.
The firmware does not provide an offload feature such
as the one used for CSA. The color change process is
hence triggered via the beacon offload tx completion
events sent out by firmware.
BSS color feature is enabled depending on service flag
advertised by firmware, based on which color change
functionality is invoked.

For 160 MHz, nss_ratio_enabled flag is added to indicate firmware
supports sending NSS ratio information from firmware as a part of
service ready ext event. Extract this NSS ratio info from service
ready ext event and save this information in ath11k_pdev_cap to
calculate NSS ratio.
Current firmware configurations support two types of NSS ratio
which is WMI_NSS_RATIO_1_NSS for QCN9074 and WMI_NSS_RATIO_1BY2_NSS
for IPQ8074. Based on this two configuration, max supported
NSS getting calculated.
Move ath11k_peer_assoc_h_phymode() before ath11k_peer_assoc_h_vht()
to get arg->peer_phymode updated.

As Hash based reo destination selection is configured,
the decapped packets reach different reo destintion rings
based on the destintaion ring selected for the computed hash (based on
the 5-tuple {ip src/ip dst/src port/dst port/protocol}) by hw and
as configured by driver.
Hence the current implementation of amsdu list based processing after all
the subframes of amsdu are received (since all msdu's for a pdev are
received in same reo dest ring), is not applicable here and hence is
replaced with per msdu based handling as these subframes
can be received in different reo dest rings.
Also, as some of the rx descriptor fields might be valid only for the
first msdu (for ex. received 80211 header, encryption type, etc),
it might not be useful now as we cannot sync between different
subframes received in different rings. Hence do not rely on those
fields and replace them with fieds valid only on per msdu descriptors.
Also cache other details such as encryption type for a peer so that
it can be reused when a packet is received from it.

This is to prepare REO ring setup before sending wmi_init command.
Firmware expects all the required REO rings to be setup while processing
wmi_init command. But as per the current initialization sequence, REO ring
configurations are done only after wmi_init command is sent.

directly to station's txrate bandwidth will cause below warning.

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.
