Merge tag 'mac80211-for-davem-2015-01-23' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Another set of last-minute fixes: * fix station double-removal when suspending while associating * fix the HT (802.11n) header length calculation * fix the CCK radiotap flag used for monitoring, a pretty old regression but a simple one-liner * fix per-station group-key handling Signed-off-by: David S. Miller <davem@davemloft.net>
