GSO like TSO is less effective when the MTU is larger. However, NICs
supporting larger MTUs also support SG. So the figures I included for

Yes, I genrally like this idea.

Hi:
This is a repost of the GSO patches. The main change is the fix to a bug
in the way dev->gso_skb is freed. This series requires the dev_deactivate

Hi:
This series adds Generic Segmentation Offload (GSO) support to the Linux
networking stack.
Many people have observed that a lot of the savings in TSO come from
traversing the networking stack once rather than many times for each
super-packet. These savings can be obtained without hardware su
