Subject: [RFC v2 net-next 2/8] net: mscc: ocelot: export MAC table lookup and write
Date: Wed, 18 Aug 2021 14:19:16 +0800	[thread overview]
Message-ID: <20210818061922.12625-3-xiaoliang.yang_1@nxp.com> (raw)
In-Reply-To: <20210818061922.12625-1-xiaoliang.yang_1@nxp.com>

Felix DSA needs to use these operations as well, for its stream
identification functions, so export them in preparation of that.
