Less important: the fact that "-net dump" is quite useful and requires
vlans. ("-net socket" has some usecases too: "-net bridge" helps placing
a VM's network on a bridge, but adding a bridge still requires root
privileges).
More important: the fact that qdev and -device really only works for ISA
and PCI devices. Boards whose NICs are sysbus devices can only add
networking with "-net nic".
