Subject: Network API now allows for multiple network devices (although the
 implementation allows for only one, and does so without compromising on the
 efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.
