Frequent crashes have been observed on MT7916 based platforms. While the
root of these crashes are currently unknown, they happen when decoding
rate information of connected STAs in AP mode. The rate-information is
associated with a band which is not available on the PHY.
Check for this condition in order to avoid crashing the whole system.
This patch should be removed once the roout cause has been found and
fixed.

(cherry picked from commit 1278d47bea)
fast-xmit must only be enabled after the sta has been uploaded to the driver,
otherwise it could end up passing the not-yet-uploaded sta via drv_tx calls
to the driver, leading to potential crashes because of uninitialized drv_priv
data.
Add a missing sta->uploaded check and re-check fast xmit after inserting a sta.

This patch will only force mac80211 loss detection upon ath10k by
masking the driver-specific loss-detection bit.

[felix.bau@gmx.de: replace path 6.2 with 5.15, refresh patches]
Signed-off-by: Felix Baumann <felix.bau@gmx.de>
ath10k does not report excessive loss in case of broken block-ack
sessions. The loss is communicated to the host-os, but ath10k does not
trigger a low-ack events by itself.
The mac80211 framework for loss detection however detects this
circumstance well in case of ath10k. So use it regardless of ath10k's
own loss detection mechanism.

When forwarding is set to 0, frames are typically sent with ttl=1.
Move the ttl decrement check below the check for local receive in order to
fix packet drops.

This helps bring down rx CPU usage by avoiding calls to the rx handlers in
the slow path. Supports forwarding and local rx, including A-MSDU.

If a packet has reached its intended destination, it was bumped to the code
that accepts it, without first checking if a mesh_path needs to be created
based on the discovered source.
Fix this by moving the destination address check further down

The standard defines the A-MSDU header length field differently for mesh
compared to other modes. Deal with this accordingly and work around broken
implementations (e.g. ath10k, ath11k).

CONFIG_MAC80211_MESH isn't defined for this package, rendering the patch
useless. Match protecting the access of sta_info.mesh with the very same

mac80211 incorrectly processes A-MSDUs contained in A-MPDU frames. This
results in dropped packets and severely impacted throughput.
As a workaround, don't indicate support for A-MSDUs contained in
A-MPDUs. This improves throughput over mesh links by factor 10.

Backports upstream fix from 5.19
lockdep complains use of uninitialized spinlock at ieee80211_do_stop() [1],
for commit f856373e2f31ffd3 ("wifi: mac80211: do not wake queues on a vif
that is being stopped") guards clear_bit() using fq.lock even before
fq_init() from ieee80211_txq_setup_flows() initializes this spinlock.
According to discussion [2], Toke was not happy with expanding usage of
fq.lock. Since __ieee80211_wake_txqs() is called under RCU read lock, we
can instead use synchronize_rcu() for flushing ieee80211_wake_txqs().
