Subject: [PATCH] wcn36xx: Fix HT40 capability for 2Ghz band
Date: Wed, 20 Oct 2021 15:38:53 +0200	[thread overview]
Message-ID: <1634737133-22336-1-git-send-email-loic.poulain@linaro.org> (raw)

All wcn36xx controllers are supposed to support HT40 (and SGI40),
This doubles the maximum bitrate/throughput with compatible APs.

Tested with wcn3620 & wcn3680B.

Cc: stable@vger.kernel.org
Fixes: 8e84c2582169 ("wcn36xx: mac80211 driver for Qualcomm WCN3660/WCN3680 hardware")
