ipvlan: assign unique dev-id for each slave device.
IPvlan setup uses one mac-address (of master). The IPv6 link-local addresses are derived using the mac-address on the link. Lack of dev-ids makes these link-local addresses same for all slaves including that of master device. dev-ids are necessary to add differentiation when L2 address is shared.
