Subject: [PATCH net-next 02/15] net: bridge: multicast: factor out bridge multicast context
From: Nikolay Aleksandrov <nikolay@...dia.com>
Factor out the bridge's global multicast context into a separate
structure which will later be used for per-vlan global context.
No functional changes intended.
