Subject: [PATCH v5 net-next 07/10] net: dsa: felix: restore multicast flood to CPU when NPI tagger reinitializes
Date: Fri, 12 Feb 2021 17:15:57 +0200 [thread overview]
Message-ID: <20210212151600.3357121-8-olteanv@gmail.com> (raw)
In-Reply-To: <20210212151600.3357121-1-olteanv@gmail.com>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
ocelot_init sets up PGID_MC to include the CPU port module, and that is
fine, but the ocelot-8021q tagger removes the CPU port module from the
unknown multicast replicator. So after a transition from the default
ocelot tagger towards ocelot-8021q and then again towards ocelot,
multicast flooding towards the CPU port module will be disabled.
Fixes: e21268efbe26 ("net: dsa: felix: perform switch setup for tag_8021q")
Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com>
