bridge: allow creating/deleting fdb entries via netlink

Browse Source 
Use RTM_NEWNEIGH and RTM_DELNEIGH to allow updating of entries
in bridge forwarding table. This allows manipulating static entries
which is not possible with existing tools.

Example (using bridge extensions to iproute2)
   # br fdb add 00:02:03:04:05:06 dev eth0
