Isn't this here so user may specify a ifindex of netdev which is not yet present on the system (not sure how much sense that would make though...)
How is this even possible? If an ifindex is not present, we return ENODEV:
if (parm->ifindex) {
dev = __dev_get_by_index(net, parm->ifindex);
if (dev == NULL) {
if (exists)
tcf_idr_release(*a, bind);
return -ENODEV;
}
