net_device::dev_id should not be used merely to indicate a VI index, as it affects the way the local part of IPv6 addresses is normally generated. This field was intended for use where multiple devices may share a single assigned MAC address and need to have different IPv6 addresses. T4 VIs each have their own MAC address.
