a bit moot because 82571 support is moving to e1000e and thus I will (probably)
not fix this bug. all 82571 support will be removed from e1000 from 2.6.26 onwards.
Please re-test against e1000e from 2.6.25-rc5 - if the bug is still in that driver
then we need to look at it again. Either that or reproduce against an 8254x adapter?
