[PATCH 00/10] wifi: ath12k: Refactor mac80211 callback operation functions

[Karthikeyan Periyasamy]

Currently, the existing mac80211 callback functions are defined assuming
each link/radio is represented by a single mac80211 hw. In order to
support multi link operation (MLO), need to move from the multi wiphy
model to a single wiphy model. However, the single wiphy model allows
multiple link/radio to be exposed by the same mac80211 hw. Therefore, we
need to separate the link/radio specific handling within the mac80211
callback operations. This way, the callback can be extended to support
multiple link/radio in the future.

In the pending branch I renamed the patch titles like this, an example:

wifi: ath12k: refactor ath12k_mac_op_conf_tx()
