I get aggregate 18Gbps with LRO v/s 12Gbps without, so it's very
much a useful feature for me.

And it'll stay like that until you work with Herbert to fix
that performance difference.

Actually I believe he's talking about hardware LRO which is a
different beast.

AFAICS the ixgbe driver doesn't use software LRO anymore.

So if it is hardware LRO then what we need is for the hardware
to switch over :)

Either way, I will be happy to test & benchmark patches of this nature
if someone wants to post them.

Thanks,
Ben
