This patch works around a recent extension of the netlink driver I had
made use of when building the netlink messages. Unfortunately older
kernels don't accept IFLA_IFNAME + name of interface as a replacement
for the interface's index, so this patch now gets the interface index
ifindex if it's not provided (ifindex <= 0).
