It is currently possible to specify things like:
-device e1000,netdev=foo,vlan=1
With this usage, whichever argument was specified last (vlan or netdev)
overwrites what was previousely set and results in a non-working
configuration. Even worse, when used with multiqueue devices,
it causes a segmentation fault on exit in qemu_free_net_client.
That patch treates the above command line options as invalid and
generates an error at start-up.
