Hi Brian,

Well, things have gone a certain distance on the TXRX on a bobcat,
however there is the problem, which I've only recently begun to grok
fully, that there is this LUC MUX FPGA chip thing that is preventing me
from using the ethernet MACs directly.

Burning question, do we have a firmware image for the LUC that will
direct map one fifo to one MAC with no LUC header required, that maybe
you guys have laying around somewhere that I can use?  Otherwise, to
get any networking to go, I would have to hack the Linux driver for the
Sibyte GigE ports to add the LUC/MUX header, and that would actually
be an arduous bunch of work.  A not-worth-it arduous bunch of work.
Which means that there would be no networking, which means there would
be no point going further with the TXRX effort.

I thought maybe there was such a thing for 2220s or for bringup/testing
or something like that me hopes.

Or maybe a board with the third Sibyte GigE port directly connected to
a MAC?  Anything?  A bobcat with no LUC?

Cheers,

a
