Subject: [V10 2/8] cfg80211: expose nl80211_chan_width_to_mhz for wide sharing
Date: Fri, 25 Aug 2023 16:38:40 +0800 [thread overview]
Message-ID: <20230825083846.4001973-3-evan.quan@amd.com> (raw)
In-Reply-To: <20230825083846.4001973-1-evan.quan@amd.com>
The newly added WBRF feature needs this interface for channel
width calculation.
