Subject: [PATCH v3 net-next 05/12] net: dsa: sync up VLAN filtering state when joining the bridge
Date: Sun, 21 Mar 2021 00:34:41 +0200
Message-ID: <20210320223448.2452869-6-olteanv@gmail.com> (raw)
In-Reply-To: <20210320223448.2452869-1-olteanv@gmail.com>

From: Vladimir Oltean <vladimir.oltean@nxp.com>

This is the same situation as for other switchdev port attributes: if we
join an already-created bridge port, such as a bond master interface,
then we can miss the initial switchdev notification emitted by the
bridge for this port.
