[PATCH ath-next v8 5/5] wifi: ath12k: fetch tx_retry and tx_failed from htt_ppdu_stats_user_cmpltn_common_tlv

[Sarika Sharma]

Currently, tx_retries and tx_failed are updated only in mac80211 during
tx_completion path for sta->deflink. This works fine for non-ML
station but for multi-link (ML) station, these values should be updated
for sta->link[link_id] as per tx link_id. However, in tx_completion path
there is no way to determine the link_id for which packet is retried or
failed.

Therefore, update the tx_retries and tx_failed in arsta structure from
htt_ppdu_stats_user_cmpltn_common_tlv during
ath12k_update_per_peer_tx_stats() call to utilize the values from arsta.
Also, during 'iw dev xxxx station dump' populate the tx_retries and
tx_failed in station_info structure to ensure values are correctly
reflected.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
