Subject: [RFC PATCH net-next 0/3] sctp: add GSO support

This patchset is merely a RFC for the moment. There are some
controversial points that I'd like to discuss before actually proposing
the patches.

The points are more detailed in the 3rd patch.

Another approach that I can think of, is using something related to
what Dave Miller mentioned on the thread 'Optimizing instruction-cache,
more packets at each stage' about skb bundling, so I Cc'ed people from
that thread too.
SCTP could generate a list of related skbs, after all that's pretty much
what this patchset does but using GRO/GSO infrastructure that is already
there.

PS: I also have code for GRO on top of this patchset, but it needs more
work yet.

Thanks!
