Actually one of my TODO items is to restructure software LRO
so that we preserve the original packet headers while aggregating
the packets. That would allow us to easily refragment them on
output for forwarding.

In other words LRO (at least the software variant) is not
fundamentally incompatible with forwarding.

I'd also like to encourage all hardware manufacturers considering
LRO support to provide a way for us to access the original headers
so that it doesn't have to be turned off for forwarding.

Cheers,
