From: Sven Eckelmann <seckelmann@datto.com>
Implement the basics required for supporting high efficiency with mesh:
include HE information elements in beacons, probe responses, and peering
action frames, and check for compatible HE configurations when peering.

From: Sven Eckelmann <seckelmann@datto.com>
Some features of 802.11ax without central organizing (AP) STA can also be
used in mesh mode. hwsim can be used to assist initial development of these
features without having access to HW.
