Okay, I've managed to get the NIC into the sluggish mode, though I'm not
exactly sure how. Below is the relevant data, including a bit of tcpdump
for an ftp fetch of the kernel. Normally this would run at about 300k per
second, but its stalling bad and running at an ETA of 60 minutes right
now:

Here's about 20 seconds of the tcpdump, notice how there's practically no
actual transfer activity:

I'm not going to reset the stack, so if you have any other tests you want
me to throw at it, let me know.
