    mac80211: Fix mac80211 station info rx bitrate for IBSS mode
    
    Filter out incoming multicast packages before applying their bitrate
    to the rx bitrate station info field to prevent them from setting the
    rx bitrate to the basic multicast rate.

    ath5k: Fix AR5K_PHY_TXPOWER_RATE_MAX register value setting.
    
    I was reading ath5k power setting code and
    noticed typing error in ath5k_hw_txpower function.
    Invalid value was written to AR5K_PHY_TXPOWER_RATE_MAX
    register.

    Add DFS interface combination only when
    CONFIG_ATH9K_DFS_CERTIFIED is set. In other case
    user can run CAC/beaconing without proper handling
    of pulse events (without radar detection activated).

    ath9k: fix race in setting ATH_OP_INVALID
    
    The commit "ath9k: move sc_flags to ath_common" moved setting
    ATH_OP_INVALID flag below ieee80211_register_hw. This is causing
    the flag never being cleared randomly as the drv_start is called
    prior to setting flag. Fix this by setting the flag prior to
    register_hw.

    ath9k: add a recv budget
    
    Implement a recv budget so that in cases of high traffic we still allow other
    taskets to get processed.
    
    Without this, we can encounter a host of issues during high wireless traffic
    reception depending on system load including rcu stall's detected (ARM),
    soft lockups, failure to service critical tasks such as watchdog resets,
    and triggering of the tx stuck tasklet.
    
    The same thing was proposed previously by Ben:
     http://www.spinics.net/lists/linux-wireless/msg112891.html
    
    The only difference here is that I make sure only processed packets are counted
    in the budget by checking at the end of the rx loop.

    ath9k: fix possible hang on flush
    
    If a flush is requested, make sure to clear the descriptor once we've
    processed it.
    
    This resolves a hang that will occur if all RX descriptors are full when a
    flush is requested.

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

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