    mac80211: allow configure_filter callback to sleep · 3ac64bee

    Over time, a whole bunch of drivers have come up
    with their own scheme to delay the configure_filter
    operation to a workqueue. To be able to simplify
    things, allow configure_filter to sleep, and add
    a new prepare_multicast callback that drivers that
    need the multicast address list implement. This new
    callback must be atomic, but most drivers either
    don't care or just calculate a hash which can be
    done atomically and then uploaded to the hardware
    non-atomically.
    
    A cursory look suggests that at76c50x-usb, ar9170,
    mwl8k (which is actually very broken now), rt2x00,
    wl1251, wl1271 and zd1211 should make use of this
    new capability.
