The rate code and rate kbps report by WMI_TLV_PEER_STATS_INFO_EVENTID
from firmware contains all the bitrate info which include OFDM, CCK,
HT/VHT, and mac80211 need the struct rate_info which include below
parameters:
flags: bitflag of flags from &enum rate_info_flags
mcs: mcs index if struct describes an HT/VHT/HE rate
legacy: bitrate in 100kbit/s for 802.11abg
nss: number of streams (VHT & HE only)
bw: bandwidth (from &enum rate_info_bw)
For OFDM/CCK, its rate kbps indicate the bitrate, for HT/VHT, mac80211
need the above 5 parameters to cacluate the bitrate and show by iw.
After parse the bitrate info, iw show the correct rx bitrate:
localhost ~ # iw wlan0 link
rx bitrate: 234.0 MBit/s VHT-MCS 3 80MHz VHT-NSS 2
rx bitrate: 40.5 MBit/s MCS 2 40MHz

For SDIO chip, its rx indication is struct htt_rx_indication_hl, which
does not include the bitrate info as well as PCIe, for PCIe, it use
function ath10k_htt_rx_h_rates to parse the bitrate info in struct
rx_ppdu_start and then report it to mac80211 via ieee80211_rx_status.
SDIO does not have the same info as PCIe, then iw command can not get
the rx bitrate by "iw wlan0 station dump".
for example, it always show 6.0 MBit/s

ADC & I/Q calibrations could take infinite time to comple, since they
depend on received frames. In particular the I/Q mismatch calibration
requires receiving of OFDM frames for completion. But in the 2.4GHz
band, a station could receive only CCK frames for a very long time.
And while we wait for the completion of one of the mentioned
calibrations, the NF calibration is blocked. Moreover, in some
environments, I/Q calibration is unable to complete until a correct
noise calibration will be performed due to AGC behaviour.
In order to avoid delaying NF calibration on forever, limit the maximum
duration of ADCs & I/Q calibrations. If the calibration is not completed
within the maximum time, it will be interrupted and a next calibration
will be performed. The code that selects the next calibration has been
reworked to the loop so incompleted calibration will be respinned later.
Ð maximum calibration time of 30 seconds was selected to give the
calibration enough time to complete and to not interfere with the long
(NF) calibration.
Run tested with AR9220.

Previously after the calibration validity period is over,
calibrations are invalidated in a one at time manner. So, for AR9002
family, which has three calibrations, the full recalibration interval
becomes 3 x ATH_RESTART_CALINTERVAL. And each next calibration will be
separated by the ATH_RESTART_CALINTERVAL time from a previous one.
It seems like it is better to do whole recalibration at once. Also, this
change makes the driver behaviour a little simpler. So, invalidate all
calibrations at once at the end of the calibration validity interval.
This change affects only AR9002 chips family, since the AR9003 utilize
only a single calibration.

NF calibration and other elements of long calibration are usually faster
than ADCs & I/Q calibrations due to independence of receiption of the
OFDM signal. Moreover sometime I/Q calibration can not be completed at
all without preceding NF calibration. This is due to AGC, which has a
habit to block a weak signal without regular NF calibration. Thus, we do
not need to deferr the long calibration forever.
So, if the long calibration is requested, then deferr the ADCs & I/Q
calibration(s) and run the longcal (the NF calibration in particular) to
obtain fresh noise data.
Run tested with AR9220.

Each of AGC & I/Q calibrations can take a long time. Long calibration
and NF calibration in particular are forbiden for parallel run with
ADC & I/Q calibrations. So, the chip could not be ready to perform the
long calibration at the time of request. And a request to perform the
long calibration may be lost.
In order to fix this, preserve the long calibration request as a
calibration state flag and restore the long calibration request each
time the calibration function is called again (i.e. on each subsequent
ivocation of the short calibration).
This feature will be twice useful after the next change, which will
make it possible to start the long calibration before all ADCs & I/Q
calibrations are completed.

ADC calibration is only required for a 80 MHz sampling rate (i.e. for
40 MHz channels), when the chip utilizes the pair of ADCs in interleved
mode. Calibration on a 20 MHz channel will never be completed.
Previous channel check is trying to exclude all channels where the
calibration will get stuck. It effectively blocks the calibration run
for HT20 channels, but fails to exclude 20 MHz channels without HT (e.g.
legacy mode channels).
Fix this issue by reworking the channel check to explicitly allow ADCs
gain & DC offset calibrations for HT40 channels only. Also update the
complicated comment to make it clear that these calibrations are for
multi-ADC mode only.
Stuck ADCs calibration blocks the NF calibration, what could make it
impossible to work in a noisy evironment: too big Rx attentuation,
invalid RSSI value, etc. So this change is actually more of a NF
calibration fix rather then the ADC calibration fix.
Run tested with AR9220.

When tx complete is disabled, all tx status will be set with status
HTT_TX_COMPL_STATE_ACK and indicate to mac80211 by ieee80211_tx_status,
then it does not have the statistics for retries and failed packets.
count of tx retries and tx failed of command "iw wlan0 station dump"
are both 0. If tx complete is not disabled, then firmware report the
tx status and ath10k indicate the status to mac80211, then mac80211
save the statistics and command "iw wlan0 station dump" show them.
for example:
localhost ~ # iw dev wlan0 station dump
Station 3c:28:6d:96:fd:69 (on wlan0)

beacon signal avg: -71 dBm
tx bitrate: 54.0 MBit/s MCS 3 40MHz
rx bitrate: 1.0 MBit/s

This patch enable firmware's extened flag of stats by setting flag
WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in
ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID.
After apply this patch, rx duration show value with the command:

tx bitrate: 54.0 MBit/s MCS 3 40MHz
rx bitrate: 1.0 MBit/s

This patch do not have side effect for all chips, because function
ath10k_debug_fw_stats_request is already exported to debugfs
"fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition
checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.

causes reo ring get full when more than 128 clients are

and reo flush command is triggered after the list count reaches
the threshold value, it is configured as 64 (half of the reo ring).

On newer hardware, the tx_queue debugfs file would need to
allocate 37.5kib data since there are 512 queues, which is
too much. Rather than resorting to kludges like kvmalloc(),
use the seq_file API to print out the data.
While at it, also fix a NULL pointer dereference here, the
txq pointer from trans_pcie->txqs[] may be NULL if that
queue hasn't been allocated.

Add support for the new WOWLAN_GET_STATUS notification that contains a
new element that informs the driver of TIDs whose BA sessions were
closed during suspend.
Note that the new functionality of handling these closed sessions is not
implemented in this patch it. It only aligns to the new API version.

The API version lookup is parsed from a TLV and should be in shared code
make make it reusable across all opmodes.
Also change the function names from mvm to fw, since this is not
mvm-specific anymore.
Additionally, since this function is not just a single line of code, it
shouldn't be inline. Convert them to actual functions.

Somehow we missed this for a long time, but similar to the extended
NSS support in VHT capabilities, we need to have this in Operating
Mode notification.
Implement it by
* parsing the 160/80+80 bit there and setting the bandwidth
appropriately
* having callers of ieee80211_get_vht_max_nss() pass in the current
max NSS value as received in the operating mode notification in
order to modify it appropriately depending on the extended NSS
bits.
This updates all drivers that use it, i.e. only iwlwifi/mvm.

Almost all drivers below cfg80211 get the API wrong (except for
cfg80211) and are unable to cope with multiple registrations for
the same frame type, which is valid due to the match filter.
This seems to indicate the API is wrong, and we should maintain
the full information in cfg80211 instead of the drivers.
Change the API to no longer inform the driver about individual
registrations and unregistrations, but rather every time about
the entire state of the entire wiphy and single wdev, whenever
it may have changed. This also simplifies the code in cfg80211
as it no longer has to track exactly what was unregistered and
can free things immediately.

Currently, wmediumd requires each used MAC address to be configured
as a station in the virtual air, but that doesn't make sense as any
station could have multiple MAC addresses, and even have randomized
ones in scanning, etc.
Add some code here to tell wmediumd of used MAC addresses, binding
them to the hardware address. Combined with a wmediumd patch that
makes it track the addresses this allows configuring just the radio
address (42:00:00:00:nn:00 unless the radio was manually created)
in wmediumd as a station, and all addresses that the station uses
are added/removed dynamically.
Tested with random scan, which without this and the corresponding
wmediumd change doesn't get anything through as the sender doesn't
exist as far as wmediumd is concerned (it's random).

When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).
Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

The driver is allowing the invalid tx/rx chainmask configuration
(other than 1,3,7,15) set by the user. It causes the firmware
crash due to the invalid chainmask values.
Hence, reject the invalid chainmask values in the driver by not
sending the pdev set command to the firmware.
