[PATCH v2 2/2] wifi: ath12k: Introduce the container for mac80211 hw

Karthikeyan Periyasamy
2024-01-12T02:42:48Z

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.
