adc47037a7
Pass multicast context pointers to multicast functions instead of bridge/port. This would make it easier later to switch these contexts to their per-vlan versions. The patch is basically search and replace, no functional changes. Signed-off-by: Nikolay Aleksandrov <nikolay@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
