An we still use it. The only difference is that we pass it the
correct device reference, which not only fixes the recursion,
but is also expected by the callbacks. Look at bonding or simply
vlan itself.

The setup itself is still done using the neigh_params passed to
VLAN, which appears to be what was originally intended.
