Merge tag 'mac80211-next-for-davem-2017-04-18' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says: ==================== My last pull request has been a while, we now have: * connection quality monitoring with multiple thresholds * support for FILS shared key authentication offload * pre-CAC regulatory compliance - only ETSI allows this * sanity check for some rate confusion that hit ChromeOS (but nobody else uses it, evidently) * some documentation updates * lots of cleanups ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
