Subject: [PATCH 4.19.y] net: dsa: mt7530: disable learning on standalone ports
Date: Tue, 24 Aug 2021 13:55:08 +0800	[thread overview]
Message-ID: <20210824055509.1316124-1-dqfext@gmail.com> (raw)

This is a partial backport of commit 5a30833b9a16f8d1aa15de06636f9317ca51f9df
("net: dsa: mt7530: support MDB and bridge flag operations") upstream.

Make sure that the standalone ports start up with learning disabled.
