Is there a way to send and receive raw ethernet packets in the kernel?

I've already created an IDE to Ethernet AISC for a mini www server, and
thought it would be fun to see if I could use the base of it as a cheap way
of throwing drives onto a system.

As long as the kernel its self has enough code to send and receive ethernet
packets (RAW) I can emulate IDE PIO and the Ethernet drive would appear to
be physically attached to the computer.
