From 7f406cd16a0f0965c761ea02bc1f03154b06bbfb Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 15 Feb 2017 15:02:09 +0100 Subject: mac80211: encode rate type (legacy, HT, VHT) with fewer bits We don't really need three different bits for each, since the types are mutually exclusive. Use just two bits for it.
