Oh, well I want to start with something that works; PLIP,
and 'port' it over to a DSP running on a PCI board. So, if
I replace the PLIP data transfer routines with my PCI
transfers, I should be able to move from something
working, to something working :)

Thats a good point. This is the first time I have played
with the lower-levels of networking layers, so hadn't
even thought of that. I'll make sure to find the relevent
ones.

That's what I figured. So in much the same way as I am
going to hook into the lowest layer of the PLIP driver,
I'll hook into the lower layer of the LwIP layers.

I just figured I'd see if anyone else out there had
tinkered with this stuff.
