>A number of ethernet devices may be supported. The default configuration
supports two instances of the interface by default,
and you will need to write your own driver instantiation code,
and supplemental startup and initialization code,
if you should add additional ones.</P

>The target for your board will normally be supplied with an
ethernet driver, in which case including the network stack and
generic ethernet driver package to your build will automatically
enable usage of the ethernet device driver.
If your target is not supplied with an ethernet
driver, you will need to use loopback (see
