Merge tag 'mac80211-next-for-davem-2015-02-03' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Last round of updates for net-next: * revert a patch that caused a regression with mesh userspace (Bob) * fix a number of suspend/resume related races (from Emmanuel, Luca and myself - we'll look at backporting later) * add software implementations for new ciphers (Jouni) * add a new ACPI ID for Broadcom's rfkill (Mika) * allow using netns FD for wireless (Vadim) * some other cleanups (various) Signed-off-by: David S. Miller <davem@davemloft.net>
