Subject: [PATCH 3/4] mac80211: minstrel_ht: fix default max throughput rate indexes
Date: Tue, 20 Aug 2019 11:54:48 +0200 [thread overview]
Message-ID: <20190820095449.45255-3-nbd@nbd.name> (raw)
In-Reply-To: <20190820095449.45255-1-nbd@nbd.name>
Use the first supported rate instead of 0 (which can be invalid)
Signed-off-by: Felix Fietkau <nbd@nbd.name>
