Some hardwares variants (QCA99x0) are limiting msdu deaggregation with
some threshold value(default limit in QCA99x0 is 64 msdus), it was introduced to
avoid excessive MSDU-deaggregation in error cases. When number of sub frames
exceeds the limit, target hardware will send all msdus starting from present
msdu in RAW format as a single msdu packet and it will be indicated with
error status bit "RX_MSDU_END_INFO0_MSDU_LIMIT_ERR" set in rx descriptor.
This msdu frame is a partial raw MSDU and does't have first msdu and ieee80211
header. It caused below warning message.

[ 320.155006] WARNING: CPU: 0 PID: 3 at drivers/net/wireless/ath/ath10k/htt_rx.c:1188
In our issue case, MSDU limit error happened due to FCS error and generated
this warning message.
This fixes the warning by handling the MSDU limit error. If msdu limit error
happens, driver adds first MSDU's ieee80211 header and sets A-MSDU present bit
in QOS header so that upper layer processes this frame if it is valid or drop it
if FCS error set. And removed the warning message, hence partial msdus without
first msdu is expected in msdu limit error cases.

Currently in 10.4 FW, all the received 4addr frames are processed for
source port learning which is enabled by default. This learning can't be
disabled by default in FW since it breaks backward compatibility.
Since ath10k uses mac80211 based 4addr mode, source port learning done in
10.4 FW is redundant and also causes issues when 3addr frames are
transmitted/received for a 4addr station.
One such visible functional impact is when GTK rekey frame from
hostapd based AP to 4addr STA is dropped in AP's 10.4 FW. This is since
GTK rekey EAPOL frame is 3addr frame on AP interface and STA enabled
with 4addr is already allowed for receiving 3addr EAPOL frames.
Source port learning implementation in 10.4 FW drops this 3addr GTK rekey
frame in AP destinated for 4addr STA causing disassociation and
re-association for every GTK rekey session. GTK rekey issue is not seen
when learning is disabled in FW.
To prevent such issues without breaking backward compatibility, FW
advertises new service bit making the source port learning configurable and
this learning is being currently disabled during ath10k vdev creation.

This issue arise in a race condition between ath10k_sta_state() and
ath10k_htt_fetch_peer_stats(), explained in below scenario
Steps:
1. In ath10k_sta_state(), arsta->tx_stats get deallocated before peer deletion
when the station moves from IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST
state.
2. Meanwhile ath10k receive HTT_T2H_MSG_TYPE_PEER_STATS message.
In ath10k_htt_fetch_peer_stats(), arsta->tx_stats get accessed after
the peer validation check.
Since arsta->tx_stats get freed before the peer deletion [1].
ath10k_htt_fetch_peer_stats() ended up in "use after free" situation.
Fixed this issue by moving the arsta->tx_stats free handling after the
peer deletion. so that ath10k_htt_fetch_peer_stats() will not end up in
"use after free" situation.

This is not an unexpected condition, so we don't need to be shouting to the

When ath6kl was reworked to share code between regular and scheduled scans
in commit 3b8ffc6a22 ("ath6kl: Configure probed SSID list consistently"),
probed SSID entry changed from 1-index to 0-indexed. However,
ath6kl_cfg80211_scan_complete_event() was missed in that change. Fix its
indexing so that we correctly clear out the probed SSID list.

Commit dd45b7598f ("ath6kl: Include match ssid list in scheduled scan")
merged the probed and matched SSID lists before sending them to the
firmware. In the process, it assumed match set support is always available
in ath6kl_set_probed_ssids, which breaks scans for hidden SSIDs. Now, check
that the firmware supports matching SSIDs in scheduled scans before setting
MATCH_SSID_FLAG.
