Merge tag 'mac80211-next-for-davem-2015-01-19' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Some further updates for net-next: * fix network-manager which was broken by the previous changes * fix delete-station events, which were broken by me making the genlmsg_end() mistake * fix a timer left running during suspend in some race conditions that would cause an annoying (but harmless) warning * (less important, but in the tree already) remove 80+80 MHz rate reporting since the spec doesn't distinguish it from 160 MHz; as the bitrate they're both 160 MHz bandwidth Signed-off-by: David S. Miller <davem@davemloft.net>
