So while messing around with tutorial 2, I found that if you run the script
normally, then run it again skipping programming, the transmit 10gbe
overflows horribly. After talking to a few people, the problem seems to be
that if you ever try to clock data into a 10gbe block while it's resetting,
it will fall over and die. Since the packet generator in tut2.mdl is just
blindly spitting out valids and end of frames, we observe this problem. Is
there a known solution for this? I'm currently just masking the valid and
end of frame lines to 0 for awhile whenever I reset the gbe block.
