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
