+
+ mac80211: exclude AP_VLAN interfaces from tx power calculation
+
+ Their power value is initialized to zero. This patch fixes an issue
+ where the configured power drops to the minimum value when AP_VLAN
+ interfaces are created/removed.

+ ath9k: fix a scheduling while atomic bug in CSA handling
+
+ Commit "ath9k: prepare for multi-interface CSA support" added a call to
+ ieee80211_iterate_active_interfaces in atomic context (beacon tasklet),
+ which is crashing.
+ Use ieee80211_iterate_active_interfaces_atomic instead.

+ ath9k_hw: reduce ANI firstep range for older chips
+
+ Use 0-8 instead of 0-16, which is closer to the old implementation.
+ Also drop the overwrite of the firstep_low parameter to improve
+ stability.
