[PATCH v2 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 v2 08/11] wifi: ath12k: delete NSS and TX power setting for monitor vdev

[Kang Yang]

ath12k_mac_monitor_vdev_create() will set NSS and TX power for monitor
vdev. But this is not needed for monitor vdev.

So delete them.

[PATCH v2 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 v2 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.

Hello,

Two quick questions there:
 - If monitor works for wcn7850 shouldn't you set supports_monitor=true in hw.c
   Or does it still require more work for it work ?
 - This whole series seems to have been tested only with wcn7850 and not qcn9274
   Is it still not supported on qcn9274 ?

Thanks
