Hi Larry, apply this patch to 3.6.8.1 and see if you get carrier errors.
Looks to me like a bug that was fixed in later drivers. Doesn't explain
why we're getting carrier errors, but this will let us moved forward to
2.4.21. What are you testing with? Do you have any newer adapters
(82544/5/6) you could try in the same setup?
