[PATCH v3 0/8] wifi: ath12k: Refactor the monitor status Rx path

[Karthikeyan Periyasamy]

Currently, the monitor status Rx path was inherited from ath11k but has
not been updated for the ath12k 802.11be hardware. Also there is no issue
at present since the monitor status Rx path is not enabled. However, in
the future, the monitor status Rx path will be enabled. Therefore, it is
necessary to update the TLV structures, bitmask definitions, remove the
unused bitmask, change the Tx monitor SRNG ring ID and refactor the
monitor status parse handler.

v3:
 - Rebsed to ToT
v2:
 - Rebsed to ToT

[PATCH v3 2/8] wifi: ath12k: Refactor monitor status TLV structure

[Karthikeyan Periyasamy]

The following TLV structures and bitmask definitions were inherited from
the ath11k but were not updated for the ath12k 802.11be hardware. These
data structure and bitmask will be used to parse the monitor status
TLV data in the Rx path.

1. hal_rx_ppdu_end_user_stats_ext structure
2. hal_rx_ppdu_end_duration structure
3. HAL_RX_HE_SIG_B2_OFDMA_INFO_INFO0_STA_TXBF bitmask
4. HAL_RX_MPDU_START_INFO1_PEERID bitmask
5. HAL_INVALID_PEERID
6. hal_rx_ppdu_end_user_stats bitmask

Currently, there is no issue since the monitor status Rx path is not
enabled. However, in the future, the monitor status Rx path will be
enabled. Therefore, update the above TLV structures and bitmask to align
with the ath12k 802.11be hardware.

[PATCH v3 3/8] wifi: ath12k: cleanup Rx peer statistics structure

[Karthikeyan Periyasamy]

Currently, unused fields are present in the Rx peer statistics
structure. These fields are already present in the same structure
under the ath12k_rx_peer_rate_stats container structure. Therefore,
remove the unused fields from the Rx peer statistics structure.

[PATCH v3 5/8] wifi: ath12k: fix incorrect TID updation in DP monitor status path

[Karthikeyan Periyasamy]

Currently, an incorrect TID value gets populated in the monitor status Rx
path due to an incorrect bitmap value given to the ffs() built-in helper
function. Therefore, avoid the decrement and directly provide the TID
bitmap to the ffs() built-in helper function for the correct TID update
in the monitor status Rx path.

The Tx monitor SRNG ring ID does not align with the ath12k 802.11be

[PATCH v3 8/8] wifi: ath12k: Avoid explicit type cast in monitor status parse handler

[Karthikeyan Periyasamy]

Currently, monitor status parse procedure handles all the supported TLV
tags. Each TLV tag has its own data structure for parsing. Now, this
handler is passed the tlv_data as a u8 pointer, so explicit type cast
conversion happens for every TLV tag parsing. Therefore, avoid the
explicit type conversion by changing the tlv_data type from a u8 pointer
to a const void pointer.
