Add MDB get attributes that correspond to the MDB set attributes used in
RTM_NEWMDB messages. Specifically, add 'MDBA_GET_ENTRY' which will hold
a 'struct br_mdb_entry' and 'MDBA_GET_ENTRY_ATTRS' which will hold
'MDBE_ATTR_*' attributes that are used as indexes (source IP and source
VNI).
An example request will look as follows:
[ struct nlmsghdr ]
[ struct br_port_msg ]
[ MDBA_GET_ENTRY ]
struct br_mdb_entry
[ MDBA_GET_ENTRY_ATTRS ]
[ MDBE_ATTR_SOURCE ]
struct in_addr / struct in6_addr
[ MDBE_ATTR_SRC_VNI ]
u32
