What about QCN9274? The commit message doesn't mention anything about
that.

I have the same question for patches 3-6. Also I would like to
understand the backwards compatibility with older WCN7850 firmwares.

For QCN9274, we reuse the same struct for them.
WIN team already checked them during internal review.

The struct definitions in patch 3-6 are hardware descriptor definition, 
won't be affected by firmware and host. They are fixed.

Please always include this information to the commit message so that we
know that you have done the research properly and the patch is not
breaking other hardware. ath12k is not only about WCN7850.

[PATCH v3 07/11] wifi: ath12k: properly handling the state variables of monitor mode

[Kang Yang]

Now monitor mode has some status variables, such as monitor_started,
monitor_vdev_created. They are not always handled correctly.

For monitor_started, it should be true when driver works in monitor
mode, and should be false at other times.

For monitor_vdev_id, it should be -1 when driver doesn't work in monitor
mode.

For monitor_vdev_created, it should be true after monitor vdev is
created successfully and should be false at other times.

For monitor_conf_enabled, it should be true when mac80211 sets
IEEE80211_CONF_MONITOR, and should be false at other times.

Handle those state variables according to above descriptions.

[PATCH v3 09/11] wifi: ath12k: use tail MSDU to get MSDU information

[Kang Yang]

When receiving a packet in monitor mode, hardware will fill status
information msdu_end for MSDUs. Then host can use these status
information to get specific information about this packet, such as
l3 offset, bandwidth, mcs, packet type.

If this packet is composed of multiple MSDUs, then hardware will only
fill status information for the last(tail) MSDU. At this time,
MSDU information is uncertain for others MSDUs. But current code use
the first MSDU in monitor mode, so will get the wrong information.

Fix it by getting msdu information from last(tail) msdu.

[PATCH v3 10/11] wifi: ath12k: fix A-MSDU indication in monitor mode

[Kang Yang]

In monitor mode, host will reap MSDUs and then the MSDUs with same PPDU
ID will be aggregated into an A-MSDU in ath12k_dp_mon_rx_merg_msdus().

However, ath12k_dp_mon_rx_merg_msdus() doesn't calculate the total
length of the A-MSDU. This causes Wireshark to display the A-MSDU
incorrectly.

Therefore, need to add calculation of the A-MSDU length.

Same question, does it fix a known issue or is just cleanup? Always
answer to the question 'why?'.

It is a clean up. Ath11k uses mon reap timer to implement rx pktlog. But 
ath12k doesn't support it yet. If we want to support, reuse the 
interrupt of monitor status ring is better. Because:
1. monitor mode also need the configuration of monitor status ring.
2. the rx pktlog is highly dependent on the implementation of monitor mode.
