That's a bummer.  I'm guessing you might get close to right on average with some
trivial math, but if someone is sending you pkts with size of 1000 and
your MTU is 1500, would there be any way to tell that the pkts were originally
1000 bytes instead of 1500?

Good point.

Well if you did GRO instead of LRO then none of this would matter :)

ixgbe uses GRO, but we have HW RSC/LRO running on 82599 adapters
underneath GRO.
