From 9df66d5b9f45c39b3925d16e8947cc10009b186d Mon Sep 17 00:00:00 2001 From: Ping-Ke Shih Date: Wed, 9 Jun 2021 15:59:44 +0800 Subject: [PATCH] cfg80211: fix default HE tx bitrate mask in 2G band In 2G band, a HE sta can only supports HT and HE, but not supports VHT. In this case, default HE tx bitrate mask isn't filled, when we use iw to set bitrates without any parameter.
