[PATCH ath-next v5 00/11] wifi: ath12k: resolve RX link id via logical link id on WCN7850/QCC2072

[Baochen Qiang]

ath12k currently relies on hardware link id to resolve the link peer. This
works for QCN9274, IPQ5332 and IPQ5424 but breaks WCN7850/QCC2072 which use
logical link id instead. Commit a2fe9dc70f3b ("wifi: ath12k: Fix low MLO RX
throughput on WCN7850") tries to fix it using peer_id but actually that fix
doesn't work always. From user PoV, current code has datapath issues like
EAPOL frames getting dropped on QCC2072, and finally MLO connection failes.

Add support for logical link id based link peer resolution to fix it.
