Commit Message

Aloka Dixit May 9, 2022, 5:33 p.m. UTC 
Modify the prototype for ieee80211_change_beacon() to accept
an instance of struct cfg80211_ap_settings instead of
struct cfg80211_beacon_data to process FILS discovery and
unsolicited broadcast probe response transmission configuration.

Set the respective flags when applicable.
