Sounds interesting.

Hardware drivers are always useful to be parallelisable even if we
currently don't tak full advantage of it. A simple example is that of
running console through network and in the same time downloading files.
In this case you require 2 simultaneous transfers.

I've also found out that pxe driver is currently attached all wrong. In
branch net I transformed it into a network protocol 'pxe' using
interface 'pxe' on dummy card 'pxe'. With UNDI the 'pxe' card will
become a card capable of sending and receiving packets.
This pushed me to remove some overkill in previous templates. I hope
that helps writing drivers.
@Manoel: even if you just put your current work without cleaning it up
it will already help. I can take care of integration.
