Subject: [PATCH 06/29] mt76: add support for an extra wiphy in mt76_sta_state()
Date: Sat, 30 Nov 2019 16:30:22 +0100	[thread overview]
Message-ID: <20191130153045.28105-6-nbd@nbd.name> (raw)
In-Reply-To: <20191130153045.28105-1-nbd@nbd.name>

This is preparation for supporting multiple wiphys per device to support the
concurrent dual-band feature of MT7615D
