[Gary Cooper]

>From 72829ea7effdf39b9d27dac21dffcf1b6e34a484 Mon Sep 17 00:00:00 2001
From: Gary Cooper <gaco at bitmessage.de>
Date: Fri, 15 Oct 2020 12:40:50 +0000
Subject: 802.11ad support

1: Daniel: As requested.
2: Robert: Your if/then-logic seems to also do the trick, this patch
achieves the same by referencing the existing logic for 802.11a/ac.
