Scenarios are:
1. Host receives ROAM_START from firmware
2. Host receives EAPOL M1 from AP, host forwarded
it to supplicant and supplicant buffered it (with
timer 100 msec) to process it after association
completion.
3. Host starts processing CP stats request, which
holds RTNL kernel lock
4. Host starts a CP_STATS_WAIT_TIME_STAT (800 msec)
timer and sends WMI_REQUEST_STATS_CMDID to FW.
So cp stats are holding the RTNL lock.
5. In waiting state host/FW completed roaming within
a few milliseconds. Host Call roamed indication
to the kernel. Kernel post it to the Work queue
to indicate this to the supplicant. The Work
queue requires the RTNL lock to send the
indication to the supplicant.
6. Now Kernel is waiting on the RTNL lock taken by
the CP stats request which is waiting for the CP
stats response (WMI_UPDATE_STATS_EVENTID).
7. Host receives CP stats response but the host is
unable to handle it with the below reason.
8. Timed out happens for WMI_UPDATE_STATS_EVENTID,
then Kernel takes RTNL lock to indicate
association/roam completion status to the
supplicant.
9. As Kernel is sending association indication
after CP_STATS_WAIT_TIME_STAT (800 msec), by
this time supplicant deleted buffered EAPOL
first frame, this results in DUT failing to
initiate the 4-WAY handshake.
10. Finally AP sends the Deauthentication frame
to DUT.
Reason for unable to process CP stats response :
As per the current design, While processing Roaming,
the host deletes the old peer and creates a new peer
for roamed AP. If the Host receives cp stats response
after peer delete due to roaming, the host is unable
to stop waiting for timer CP_STATS_WAIT_TIME_STAT
and fails to release RTNL kernel lock till timeout.
After time out only, Kernel can take RTNL lock to
indicate association/roam completion status to the
supplicant.
Fix is to stop the wait timer CP_STATS_WAIT_TIME_STAT
and release RTNL kernel lock even in case peer has
deleted by HOST for which CP stats request sent.

If macro WLAN_FEATURE_11BE_MLO is enable, get_station_stats_cb for
TYPE_STATION_STATS is called only if last_req->ml_vdev_info.ml_vdev_count
none zero when WMI_UPDATE_STATS_EVENTID event comes back.
This causes timeout and fail to get station stats for legacy device or for
MLO device which does not set last_req->ml_vdev_info.ml_vdev_count.
To resolve this issue, add sanity check legacy device before invoking the
callback and set last_req->ml_vdev_info.ml_vdev_count if it is MLO device.

In P2P connect process, GO and GC send deauth/disassoc at the
end of WPS. GO send disassoc and free station info. GO receive
deauth from GC, and send cmd WLAN_SER_CMD_GET_DISCONNECT_STATS
to get disconnect stats.
If GO send deauth and free peer info before receive deauth
from GC. Wlan_objmgr_get_peer return null, and peer is null.
Cmd of WLAN_SER_CMD_GET_DISCONNECT_STATS will never be
released since get_peer_rssi_cb will never be called.
And cmd will timeout, which is not expected.
If we call get_peer_rssi_cb without check, cmd will release.
Also csr_get_peer_rssi_cb will check peer is null or not.
