Sorry for the delay, i had to do an onsite thing in another country, so
i first see your message now.

Would it be okay if i took rc9 instead? also, i saw you posted a set of
patches to sync more with realteks code, is this something you would
like me to test too, or aswell? (remember, i have the 8111c).

Btw, a thought just crossed my mind as to a possible reason why this
might be happening, i was googling around, and it seems the TWO nic's
are supposed to have some sort of hardware bonding thing, could it be
because such stuff isnt handled?

mvh.
