The usb_drv is almost ready to support multiple NICs. Currently a NIC
device can be associated to a NIC session. What the driver is lacking,
is configuration support in Genode's configuration file. There one would
want to specify which client will receive which NIC session when
connecting to the USB server, but that could be implemented pretty
straight forward. Multiplexing is not necessary, since the NIC device is
associated to the session. When a device interrupt occurs, the device
will report it to the session and the session in turn to the client.
