To: ath12k; +Cc: linux-wireless, Karthikeyan Periyasamy
Currently, mac80211 hardware accesses link/radio structure directly in
multiple locations. Introduce helper function to avoid this direct
access, as this change will facilitate refactoring for Multi-link
operation support.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

To: ath12k; +Cc: linux-wireless, Karthikeyan Periyasamy
To support multi link operation, we need to combine all the link/pdev
under a single wiphy. This avoids the overhead of synchronization
across multiple hardware instances in both the cfg80211 and mac80211
layers. Currently, each link/pdev is registered as separate wiphy,
tightly coupled with link/pdev/radio (ar) structure. To enable single
wiphy registration within the chip, we decouple the wiphy data entity from
the link/pdev/radio (ar) structure and move it under the chip (ab)
structure with a new data container (ath12k_hw) structure. This approach
improves scalability for future multi link operation support.
