neigh: add function to look up neighbour (fdb) by ifindex, mac and vlan
The rtnl_neigh_get() function can not be used to look up a fdb entry in the
neigh cache. This is due to that the function searches among destination
addresses (NDA_DST) and not among link layer addresses (NDA_LLADDR), which is
used by fdb entries. A fdb entry can also exist in several vlans, so a vlan id
parameter is also needed to find a unique entry.
This commit adds a function, rtnl_neigh_get_by_vlan() which searches the neigh
cache for a specific neighbour (fdb) entry by interface index, link layer
address and vlan id.
