2d96374ca3 qca-wifi: Memory optimization for PPDU stats
Currently, per-user information in Tx PPDU completion is allocated for
37 users though FW may send information for fewer number of users. In
new scheme, FW provides number of users in USERS_INFO TLV and host can
allocate the per-user struct based on this number. This can save memory
while processing each completion message.
Make related changes in tx capture files to use pointer instead of fixed
size member.

aa3e76eb38 qca-wifi: Avoid processing of PPDU USER multiple times in Tx capture
Currently, same user can be processed multiple times, which leads to
release ref count wrongly, with this, some of the users in PPDU
desc are never processed and can possibly cause memory leak.

Added a flag in PPDU user to indicate that the user is already
processed.

cf092b85d9 qca-wifi: Add sched_cmdid check for tx cap retry queue
Before adding a ppdu to the retry queue, check if the
sched_cmdid matches that of the first ppdu in the queue.
If it does not, then the retry queue should be freed as
the received ppdu is not a retry of the ppdu in the queue.

cf78ddd987 qca-wifi: Add frame types to TX Capture
The current implementation of the TX Capture
feature assumes a non QoS 3 address frame for
each frame. If a frame is a QoS frame, the extra
fields are manually added, but if the frame is a
4 address frame, there is no handling. Add QoS,
4 address and 4 address QoS frame types to the
TX Capture feature and update accordingly.

d0aafa3624 qca-wifi: Tx capture stability fixes
1) Avoid removing wrong nbuf from queue
   In corner case, the current flow can remove first nbuf instead of
   actual nbuf from queue, this can lead to having the actual pointer
   stored at two array indexs.

2) tsf wraparound handling for mgmt frame

3) Mpdu tried is higher than ba_sisze
   mpdus[] is allocated with ba_size, it is observed that mpdu_tried
   is higher than ba_size, which can lead to buffer overlow.
   Added the check of ba_size along with mpdu_tried.

To avoid it, copied nbuf in the corner case, and left the actual nbuf
in the xretries queue.
