Commit Message

Aloka Dixit Nov. 9, 2022, 9:47 p.m. UTC
Modify the prototype for change_beacon() in struct cfg80211_op to
accept struct cfg80211_ap_settings instead of cfg80211_beacon_data
so that it can process data in addition to beacons.
Above change also requires similar modifications to prototype of
ieee80211_change_beacon() and driver specific functions for
successful compilation.
