Currently ar->ht_cap_info is not set anywhere in the code, this could
result in LDPC config computed wrongly in the set_bitrate_mask() hook
and eventually sending wrong config to the target. Fix this by checking
the LDPC support from the band HT capabilities of the radio instead.
Furthermore, it looks like firmwares running on the ath11k hardware
do not set WMI_HT_CAP_LDPC for advertising the TX LDPC capability,
WMI_HT_CAP_TX_LDPC is set instead and this should be checked for
getting hardware's TX LDPC support. This is true for QCA6390, WCN6855
& WCN6750 hardware.
Also, remove unused variables ht_cap_info & vht_cap_info from
struct ath11k{}.
Found this during code review.

Currently when firmware recovery is in progress, we do not queue REO
commands to the firmware, instead -ESHUTDOWN will be returned to the
caller leading to a failure print on the console. The REO command in
the problem scenario is sent for all tids of a peer in which case we
will have 16 failure prints on the console for a single peer. For an
AP usecase, this count would be even higher in a worst case scenario.
Since these commands are bound to fail during firmware recovery, it
is better to avoid printing these failures and thereby avoid message
flooding on the console.

Currently a couple of debug_mask entries are mapped to the same value,
this could enable unintended driver logging. If enabling DP_TX logs was
the intention, then this could also enable PCI logs flooding the dmesg

On htc_tx_completion error the skb is not dropped. This is wrong since
the completion_handler logic expect the skb to be consumed anyway even
when an error is triggered. Not freeing the skb on error is a memory

The initial reg code is 0x6C which saved in reg_world_copy of ath_common,
and the code US is updated from cfg80211 later, so ath10k should also

then update_all_wiphy_regulatory() will not be called while wlan load.
When run "iw reg set xx", reg_get_regdomain() which used by function

Frame encapsulation from Ethernet into the IEEE 802.11 frame format
takes a considerable host CPU time on the xmit path. The firmware is
able to do this operation for us, so enable encapsulation offloading for
AP and Sta interface types to improve overall system performance.
The driver is almost ready for encapsulation offloading support. There
are only a few places where the driver assumes the frame format is IEEE
802.11 that need to be fixed.
Encapsulation offloading is currently disabled by default and the driver
utilizes mac80211 encapsulation support. To activate offloading, the
frame_mode=2 parameter should be passed during module loading.
On a QCA9563+QCA9888-based access point in bridged mode, encapsulation
offloading increases TCP 16-streams DL throughput from 365 to 396 mbps
(+8%) and UDP DL throughput from 436 to 483 mbps (+11%).

The xmit path for the Ethernet encapsulated frames become more or less
usable since d740d8fd24 ("ath10k: unify tx mode and dispatch"). This
change reorganize the xmit path in a manageable way to properly support
various tx modes, but misses that the Ethernet encapsulated frame is a
special case. We do not have an IEEE 802.11 header at the begining of
them. But the HTT Tx handler still interprets first bytes of each frame
as an IEEE 802.11 Frame Control field.
Than this code was copied by e62ee5c381 ("ath10k: Add support for
htt_data_tx_desc_64 descriptor") and a2097d6444 ("ath10k: htt: High
latency TX support") to another handlers. In fact the issue in the high
latency (HL) handler was introduced by 83ac260151 ("ath10k: add mic
bytes for pmf management packet").
Ethernet encapsulated frame tx mode stay unused until 75d85fd999
("ath10k: introduce basic tdls functionality") started using it for TDLS
frames to avoid key selection issue in some firmwares.
Trying to interpret the begining of an Ethernet encapsulated frame as an
IEEE 802.11 header was not hurt us noticeably since we need to meet two
conditions: (1) xmit should be performed towards a TDLS peer, and (2)
the TDLS peer should have a specific OUI part of its MAC address. Looks
like that the rareness in TDLS communications of OUIs that can be
interpreted as an 802.11 management frame saves users from facing this
issue earlier.
Improve Ethernet tx mode support in the HTT Tx handler by avoiding
interpreting its first bytes as an IEEE 802.11 header. While at it, make
the ieee80211_hdr variable local to the code block that is guarded by
!is_eth check. In this way, we clarify in which cases a frame can be
interpreted as IEEE 802.11, and saves us from similar issues in the
future.
Credits: this change as part of xmit encapsulation offloading support
was originally made by QCA and then submitted for inclusion by John
Crispin [1]. But the whole work was not accepted due to the lack of a
part for 64-bits descriptors [2]. Zhijun You then pointed this out to me
in a reply to my initial RFC patch series. And I made this slightly
reworked version that covered all the HTT Tx handler variants.

We use ieee80211_tx_status() to report each completed tx frame.
Internally, this function calls sta_info_get_by_addrs(), what has a
couple of drawbacks:
1. additional station lookup causes a performance degradation;
2. mac80211 can not properly account Ethernet encapsulated frames due
to the inability to properly determine the destination (station) MAC
address since ieee80211_tx_status() assumes the frame has a 802.11
header.
The latter is especially destructive if we want to use hardware frames
encapsulation.
To fix both of these issues, replace ieee80211_tx_status() with
ieee80211_tx_status_ext() call and feed it station pointer from the tx
queue associated with the transmitted frame.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge rising - but instead rely on Devicetree to configure it.
All Qualcomm DTSI with WCN3990 define the interrupt type as level high,
so the mismatch between DTSI and driver causes rebind issues:

This patch adds support for the new struct ieee80211_rate_status and its
annotation in struct ieee80211_tx_status in minstrel_ht.
In minstrel_ht_tx_status, a check for the presence of instances of the
new struct in ieee80211_tx_status is added. Based on this, minstrel_ht
then gets and updates internal rate stats with either struct
ieee80211_rate_status or ieee80211_tx_info->status.rates.
Adjusted variants of minstrel_ht_txstat_valid, minstrel_ht_get_stats,
minstrel_{ht/vht}_get_group_idx are added which use struct
ieee80211_rate_status and struct rate_info instead of the legacy structs.
struct rate_info from cfg80211.h does not provide whether short preamble
was used for the transmission. So we retrieve this information from VIF
and STA configuration and cache it in a new flag in struct minstrel_ht_sta
per rate control instance.

This patch adds the new struct ieee80211_rate_status and replaces
'struct rate_info *rate' in ieee80211_tx_status with pointer and length
annotation.
The struct ieee80211_rate_status allows to:
(1) receive tx power status feedback for transmit power control (TPC)
per packet or packet retry
(2) dynamic mapping of wifi chip specific multi-rate retry (mrr)
chains with different lengths
(3) increase the limit of annotatable rate indices to support
IEEE802.11ac rate sets and beyond
ieee80211_tx_info, control and status buffer, and ieee80211_tx_rate
cannot be used to achieve these goals due to fixed size limitations.
Our new struct contains a struct rate_info to annotate the rate that was
used, retry count of the rate and tx power. It is intended for all
information related to RC and TPC that needs to be passed from driver to
mac80211 and its RC/TPC algorithms like Minstrel_HT. It corresponds to
one stage in an mrr. Multiple subsequent instances of this struct can be
included in struct ieee80211_tx_status via a pointer and a length variable.
Those instances can be allocated on-stack. The former reference to a single
instance of struct rate_info is replaced with our new annotation.
An extension is introduced to struct ieee80211_hw. There are two new
members called 'tx_power_levels' and 'max_txpwr_levels_idx' acting as a
tx power level table. When a wifi device is registered, the driver shall
supply all supported power levels in this list. This allows to support
several quirks like differing power steps in power level ranges or
alike. TPC can use this for algorithm and thus be designed more abstract
instead of handling all possible step widths individually.
Further mandatory changes in status.c, mt76 and ath11k drivers due to the
removal of 'struct rate_info *rate' are also included.
status.c already uses the information in ieee80211_tx_status->rate in
radiotap, this is now changed to use ieee80211_rate_status->rate_idx.
mt76 driver already uses struct rate_info to pass the tx rate to status
path. The new members of the ieee80211_tx_status are set to NULL and 0
because the previously passed rate is not relevant to rate control and
accurate information is passed via tx_info->status.rates.
For ath11k, the txrate can be passed via this struct because ath11k uses
firmware RC and thus the information does not interfere with software RC.

We currently track whether we're associated and which the
BSS is in the same variable (ifmgd->associated), but for
MLD we'll need to move the BSS pointer to be per link,
while the question whether we're associated or not is for
the whole interface.
Add ifmgd->assoc_bss that stores the pointer and change
ifmgd->associated to be just a bool, so the question of
whether we're associated can continue working after MLD
rework, without requiring changes, while the BSS pointer
will have to be changed/used checked per link.

Since we always track the BSSID there when we get associated,
these are equivalent, but ifmgd->bssid saves a dereference and
thus makes the code a bit smaller, and more readable.
