   5     ath9k: remove tid->paused flag
   6
   7     There are some corner cases where the driver could get stuck with a full
   8     tid queue that is paused, leading to a software tx queue hang.
   9
  10     Since the tx queueing rework, pausing per-tid queues on aggregation
  11     session setup is no longer necessary. The driver will assign sequence
  12     numbers to buffered frames when a new session is established, in order
  13     to get the correct starting sequence number.
  14
  15     mac80211 prevents new frames from entering the queue during setup.

  23     ath9k_hw: do not lower ANI setting below default on AR913x
  24
  25     When the amount of noise fluctuates strongly, low immunity settings
  26     can sometimes disrupt signal detection on AR913x chips. When that
  27     happens, no OFDM/CCK errors are reported anymore, and ANI tunes the
  28     radio to the lowest immunity settings.
  29     Usually rx/tx fails as well in that case.
  30
  31     To fix this, keep noise immunity settings at or above ANI default level,
  32     which will keep radio parameters at or above INI values.

  40     mac80211: exclude AP_VLAN interfaces from tx power calculation
  41
  42     Their power value is initialized to zero. This patch fixes an issue
  43     where the configured power drops to the minimum value when AP_VLAN
  44     interfaces are created/removed.

  63     ath9k: fix a scheduling while atomic bug in CSA handling
  64
  65     Commit "ath9k: prepare for multi-interface CSA support" added a call to
  66     ieee80211_iterate_active_interfaces in atomic context (beacon tasklet),
  67     which is crashing.
  68     Use ieee80211_iterate_active_interfaces_atomic instead.

  76     ath9k_hw: reduce ANI firstep range for older chips
  77
  78     Use 0-8 instead of 0-16, which is closer to the old implementation.
  79     Also drop the overwrite of the firstep_low parameter to improve
  80     stability.
