Add the tap driver.
The tap driver is used to present a virtual Ethernet interface to the
system. Packets presented by the network stack to the interface are
made available to a character device in /dev. With tap and the bridge
code, you can make remote bridge configurations where both sides of
the bridge are separated by userland daemons.
This driver also has a special naming hack to allow it to serve a similar
purpose to the vmware port.
