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.

TIA,

Krishna


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.
