+    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.
