Subject: [PATCH 18/24] cfg80211: reject HT/VHT capabilities on 6 GHz band
Date: Thu, 28 May 2020 16:50:14 +0200	[thread overview]
Message-ID: <20200528165011.7ad191cbf552.Ibba5e066fa0087fd49d13cfee89d196ea0c68ae2@changeid> (raw)
In-Reply-To: <20200528165011.993f108e96ca.I0086ae42d672379380d04ac5effb2f3d5135731b@changeid>

From: Johannes Berg <johannes.berg@intel.com>

On the 6 GHz band, HE should be used, but without any direct HT/VHT
capabilities, instead the HE 6 GHz band capabilities will capture
the relevant information. Reject HT/VHT capabilities here.
