Johannes Berg says:

====================
Another set of updates, all over the map:
 * set sk_pacing_shift for 802.3->802.11 encap offload
 * some monitor support for 802.11->802.3 decap offload
 * HE (802.11ax) spec updates
 * userspace API for TDLS HE support
 * along with various other small features, cleanups and
   fixups
====================
