Subject: [PATCH net-next v16 4/6] net: dsa: mv88e6xxx: wrap .set_egress_port method
Date: Thu, 14 Jan 2021 05:33:29 +0100	[thread overview]
Message-ID: <20210114043331.4572-5-kabel@kernel.org> (raw)
In-Reply-To: <20210114043331.4572-1-kabel@kernel.org>

There are two implementations of the .set_egress_port method, and both
of them, if successful, set chip->*gress_dest_port variable.

To avoid code repetition, wrap this method into
mv88e6xxx_set_egress_port.
