From ccedf8163fa66f2db85d863a43f056ac69a5fef5 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 [ Upstream commit 9df66d5b9f45c39b3925d16e8947cc10009b186d ] 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.
