Subject: [PATCH v3 02/22] nl80211: advertise supported channel width in S1G
Date: Tue, 8 Sep 2020 12:03:03 -0700 [thread overview]
Message-ID: <20200908190323.15814-3-thomas@adapt-ip.com> (raw)
In-Reply-To: <20200908190323.15814-1-thomas@adapt-ip.com>
S1G supports 5 channel widths: 1, 2, 4, 8, and 16. One
channel width is allowed per frequency in each operating
class, so it makes more sense to advertise the specific
channel width allowed.
