Hi experts,

We have to design a special device....to implement a special protocol
on top of ethernet. Rabbit 4k devices look like a good choice, but it
comes with TCP/IP stack built in.

How easy it is in Rabbit 4K to get rid of the the TCP/IP stack from
OS
and take charge of packets arriving over ethernet.

I am aware of NE2000 compatibility. Please let me know whether it
will
be helpful and any other pointers will be of big help.

The source code for the tcp/ip stuff is included, so it will be
a convenient starting point for writing your own drivers. As
far as I know if you never do the calls to set up the tcp/ip
stack, it's never going to get in the way of whatever driver
you write. Talking to the on-board ethernet hardware is
pretty simple with or without dma.

Hi Monte. Nice job, sir. I've used the Rabbits, and have been very happy
with them. (This from someone who has otherwise learned the hard way to
be very wary of 3rd-party embedded code ;).)

And welcome to the ng.

Why, thank you. I've been lurking here for years, but seldom have
anything to contribute.
