From 461ce35d5535c1479384f67fcf4bfc3f3610edca Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 28 May 2020 21:34:41 +0200 Subject: cfg80211: reject HT/VHT capabilities on 6 GHz band 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.
