bridge: add MDB get uAPI attributes
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 Signed-off-by: Ido Schimmel <idosch@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S. Miller <davem@davemloft.net>
