About Vikram's 10/100 mode question, we were wondering if it's a design flaw;
i.e. something wrong from the start in
the original opencores.org source, or if it's fixable but hasn't been a high
priority item given USRP2's high data
rate requirements. But then I found this post:

So I guess the former. If there are any hints you can give on what's wrong, we
can take a look. Maybe our guys can
get it working.
Eventually I got completely fed up with the opencores gige core and
wrote a completely new one from scratch (the simple_gemac). It only
does gigabit, though.
One of the main problems with 10/100/1000 in a spartan is that you need
a large number of clocks and the S3 is constrained. If you just want
10/100 and can live without gigabit, I would suggest doing that, as it
will save 1 or 2 clocks.
