[PATCH net-next v3 05/11] net/smc: implement some unsupported operations of loopback-ism

vlan operations are not supported currently since the need for vlan in
loopback-ism situation does not seem to be strong.

signal_event operation is not supported since no event now needs to be
processed by loopback-ism device.
