    mac80211: fix queue handling crash · 2b436312
    Johannes Berg authored
    The code I added in "mac80211: don't start new netdev queues
    if driver stopped" crashes for monitor and AP VLAN interfaces
    because while they have a netdev, they don't have queues set
    up by the driver.
    To fix the crash, exclude these from queue accounting here
    and just start their netdev queues unconditionally.
    For monitor, this is the best we can do, as we can redirect
    frames there to any other interface and don't know which one
    that will since it can be different for each frame.
    For AP VLAN interfaces, we can do better later and actually
    properly track the queue status. Not doing this is really a
    separate bug though.
