As a followup, I've meanwhile gotten the packet layer for the internal
ethernet module working.  It was easier than I expected.  Once I fixed two
MOVFF I accidentally typed as MOVF, everything worked.  So far I have only
tested it by PINGing the board from my PC.  That tests the packet layer, ARP
replies, and ICMP PING replies.  I didn't change anything in the upper
levels, so I assume the ARP cache, IP, and TCP are working too.  I'll
eventually test it more thouroghly, but for now I'm on to the ZeroG module.

I haven't decided how the code will be released, if at all.  If you want it
just for personal use you can have it now.  I have three boards and have so
far populated just the one I'm working with.  You can have one of the bare
boards if you're serious about using it.  You'll have to acquire the parts
and build it up yourself.

This is all in MPASM with my development environment.  I expect to use this
as a low level capability for future projects not yet dreamed up, so I want
this code to be as light weight and low footprint as possible.  However, it
is possible to call this stuff from C18.  I've done that with a customer
project using Microchip's HTTP server, which is in C18.  I had to create a
few glue routines, but it was pretty simple.

That's why I started with the wired ethernet module too.  I wanted to make
sure everything was OK above the packet layer before creating the ZeroG
packet layer.
