net: dsa: b53: Add support for MDB
In preparation for supporting IGMP snooping with or without the use of a bridge, add support within b53_common.c to program the ARL entries for multicast operations. The key difference is that a multicast ARL entry is comprised of a bitmask of enabled ports, instead of a port number. Signed-off-by:Florian Fainelli <f.fainelli@gmail.com> Reviewed-by:
