I am in the process of replacing the old GigE MAC logic for the USRP2 with a
much cleaner design.  This is the first step in allowing for a bunch of big
improvements.  I would greatly appreciate it if people with USRP2s would try
this new version.  Instructions on how to get it are here:


Please report both success or problems with it.

Is this a completely new re-write or reworking what was originally
from opencores?

This is a complete removal of the entire GigE MAC from OpenCores. The MDIO (actually from the OpenCores 10/100 core) remains, but that's it.

While I was at it, I rewrote all the FIFOs, the buffer pool interface, and a few other things in there as well. From the user's point of view, everything should function exactly the same and you shouldn't be able to tell the difference. If there is any different behavior please let me know.
