This is a preparation for supporting Multi-Link reconfigure link removal
procedure[IEEE P802.11be/D5.0 - 35.3.6.3 Removing affiliated APs] for
driver which supports offloaded Multi-Link reconfigure link removal.

Multi-Link reconfigure link removal offloaded drivers will take care
of updating the reconfiguration MLE in self and partner beacons. It
also updates the AP removal timer automatically and notifies once the
counter is expired.

This patchset also adds mac80211 routine to support sending link
removal command from userspace to offloaded driver which accepts
reconfigure Multi-Link element and the TBTT count for the link to be
removed.

Driver (ath12k) changes that utilize this will be posted in the future
versions.

    link removal offload
  wifi: mac80211: Add support for link reconfigure removal
