Subject: [PATCH] iw: enable 80MHz support for 6GHz band 11s mesh
Date:   Fri,  9 Oct 2020 15:49:30 -0700
Message-Id: <1602283770-8026-2-git-send-email-pradeepc@codeaurora.org>
In-Reply-To: <1602283770-8026-1-git-send-email-pradeepc@codeaurora.org>
References: <1602283770-8026-1-git-send-email-pradeepc@codeaurora.org>
Precedence: bulk

without this 11s mesh could not be configured with bandwidth 80MHz
in 6G band using iw. Also, this will be required to set frequency
for 6GHz band in 80MHz.

example:
iw <interface> mesh join <meshname> freq 6195 80MHz
