This patchset adds sctp GSO support. Performance tests indicates that increases throughput by 10% if using bigger chunk sizes, specially if bigger than MTU. For small chunks, it doesn't help much if not using heavy firewall rules.
For small chunks it will probably be of more use once we get something like MSG_MORE as David Laight had suggested. I believe I could address all comments from the RFC attempt.
