Merge tag 'mac80211-for-davem-2017-02-28' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
First round of fixes - details in the commits:
* use a valid hrtimer clock ID in mac80211_hwsim
* don't reorder frames prior to BA session
* flush a delayed work at suspend so the state is all valid before
suspend/resume
* fix packet statistics in fast-RX, the RX packets
counter increment was simply missing
* don't try to re-transmit filtered frames in an aggregation session
* shorten (for tracing) a debug message
* typo fix in another debug message
* fix nul-termination with HWSIM_ATTR_RADIO_NAME in hwsim
* fix mgmt RX processing when station is looked up by driver/device
====================
