Merge tag 'mac80211-for-davem-2017-06-13' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
Some fixes:
* Avi fixes some fallout from my mac80211 RX flags changes
* Emmanuel fixes an issue with adhering to the spec, and
an oversight in the SMPS management code
* Jason's patch makes mac80211 use constant-time memory
comparisons for message authentication, to avoid having
potentially observable timing differences
* my fix makes mac80211 set the basic rates bitmap before
the channel so the next update to the driver has more
consistent data - this required another rework patch to
remove some useless 5/10 MHz code that can never be hit
====================
