    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.
