This patchset adds MDB get support, allowing user space to request a
single MDB entry to be retrieved instead of dumping the entire MDB.
Support is added in both the bridge and VXLAN drivers.
Patches #1-#6 are small preparations in both drivers.
Patches #7-#8 add the required uAPI attributes for the new functionality
and the MDB get net device operation (NDO), respectively.
Patches #9-#10 implement the MDB get NDO in both drivers.
Patch #11 registers a handler for RTM_GETMDB messages in rtnetlink core.
The handler derives the net device from the ifindex specified in the
ancillary header and invokes its MDB get NDO.
Patches #12-#13 add selftests by converting tests that use MDB dump with
grep to the new MDB get functionality.
iproute2 changes can be found here [1].
