USB network cards

A lot of modern laptops don't have RJ45 jacks.  Ethernet is only
supported via USB Ethernet adapters.

Is this just a special case of broader USB support, or is it worth
handling separately?  If the Linux USB core and the xHCI driver were
secure against malicious input, it might make sense to implement
the drivers in userspace on the router.  Sadly, that isn't the case
right now.

I don't immediately see a reason it would need to be handled separately.
The router VM shouldn't care whether a network device is USB or not.
What special handling do you imagine?
