Subject: [PATCH net-next 13/15] net: bridge: vlan: add support for mcast router global option
Date: Tue, 10 Aug 2021 18:29:31 +0300 [thread overview]
Message-ID: <20210810152933.178325-14-razor@blackwall.org> (raw)
In-Reply-To: <20210810152933.178325-1-razor@blackwall.org>
From: Nikolay Aleksandrov <nikolay@nvidia.com>
Add support to change and retrieve global vlan multicast router state
which is used for the bridge itself. We just need to pass multicast context
to br_multicast_set_router instead of bridge device and the rest of the
logic remains the same.
