Series wifi: cfg80211/mac80211: add link_id handling in AP channel switch during Multi-Link Operation | expand

Commit Message

Aditya Kumar Singh Jan. 30, 2024, 2:09 p.m. UTC 
Currently, during channel switch, no link id information is passed down.
In order to support channel switch during Multi Link Operation, it is
required to pass link id as well.

Add changes to pass link id in the channel_switch cfg80211_ops.
