bridge: mdb: Add routing protocol support
Allow user space to specify the routing protocol of the MDB port group
entry by adding the 'MDBE_ATTR_RTPROT' attribute to the
'MDBA_SET_ENTRY_ATTRS' nest.
Examples:
# bridge mdb add dev br0 port dummy10 grp 239.1.1.1 permanent proto zebra
# bridge mdb add dev br0 port dummy10 grp 239.1.1.2 permanent
# bridge -d mdb show
dev br0 port dummy10 grp 239.1.1.2 permanent filter_mode exclude proto static
dev br0 port dummy10 grp 239.1.1.1 permanent filter_mode exclude proto zebra
