In this specific case, the host isn't actually affected; only the MC can
lose connectivity if the driver doesn't detect the MC due to this bug and
powers down/resets the interface when it shouldn't.
Bugs that led to the host losing connectivity were fixed in or before
2.6.32.
This patch is entirely safe to apply, per 82575 documentation and the fact
that it comes straight from Intel ;)
Thanks,
JB.
