Good question. With ipsec, GRO (like GSO) gets implicitly disabled.
But when I explictly disable GRO on receiver, leaving only GSO
on sender, I can still get about 6 Gbps for clear traffic.
Thus if I could get closer to 6 Gbps for my patch, I'd at least
know that it was just GRO that was missing.. but I'm only getting
3 Gbps, which makes me think I missed something else on the sender
itself.
