Merge tag 'mac80211-for-davem-2016-12-16' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:

====================
Three fixes:
 * avoid a WARN_ON() when trying to use WEP with AP_VLANs
 * ensure enough headroom on mesh forwarding packets
 * don't report unknown/invalid rates to userspace
====================
