Merge tag 'mac80211-next-for-davem-2018-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Small merge conflict in net/mac80211/scan.c, I preserved
the kcalloc() conversion. -DaveM
Johannes Berg says:
====================
This round's updates:
* finally some of the promised HE code, but it turns
out to be small - but everything kept changing, so
one part I did in the driver was >30 patches for
what was ultimately <200 lines of code ... similar
here for this code.
* improved scan privacy support - can now specify scan
flags for randomizing the sequence number as well as
reducing the probe request element content
* rfkill cleanups
* a timekeeping cleanup from Arnd
* various other cleanups
====================
