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

Currently, during channel switch, deflink (or link_id 0) is always
considered. However, with Multi-Link Operation (MLO), there is a
need to handle link specific data structures based on the actual
operational link_id during channel switch operation.

Hence, add support for the same. Non-MLO based operations will use
link_id as 0 or deflink member as applicable.

While at it, beacon count down now needs to be updated on proper
link_id's beacon, do that as well.

Aditya Kumar Singh (5):
  wifi: cfg80211: send link id in channel_switch ops
  wifi: mac80211: update beacon counters per link basis
  wifi: mac80211: handle set csa/after_csa beacon on per link basis
  wifi: mac80211: start and finalize channel switch on link basis
  wifi: mac80211: add support to call csa_finish on a link

v8: * fixed space error in documentation in 1/5
    * minor commit message rephrasing in 3/5 and 5/5.

v7: * fixed proper link id validation in 2/5 and 5/5. (>=)
    * added comma in trace print in 1/5

v6: * splitted v5 2/3 into v6 3/5, 4/5 and 5/5
    * rephrased commit mesage in 1/5

v5: * fixed compilation issue reported by kernel test robot.

v4: * fixed compilation issue reported by kernel test robot.
    * rebased on latest ToT.
    * moved link_id arguement into csa_params struct in [1/3]

v3: * splitted [v2 1/2] into [v3 1/3] and [v3 2/3] having simple cfg80211
      changes in 1/3 for easy review. Rest in 2/3 [Johannes]
    * used wiphy_dereference() instead of sdata_dereference() [Johannes]

v2: * reabsed on ToT
    * removed unwanted locking sequence during cancelling CSA work handler
      since now locking is moved to wiphy level, that part is uncessary now.
