[PATCH 8/9] ath11k: EMA beacon support
Aloka Dixit

Sun May 22 23:01:07 PDT 2022
Add new function ath11k_mac_setup_bcn_tmpl_ema() which invokes the new
API provided by MAC80211 to retrieve EMA beacons. For non EMA APs,
ath11k_mac_setup_bcn_tmpl_legacy() is added which maintains the current
functionality.
