        I forgot to mention that this patchset follows the
"ipvs: sloppy TCP and SCTP" change from Alexander Frolkin
posted on June 13. Our plans are for following list:

1. ipvs: sloppy TCP and SCTP (posted by Alexander and acked by me)
2. ipvs: provide iph to schedulers (just applied by you)
3. SH changes by Alexander (to be posted officially) depend
on 1 and 2 while SCTP patchset by me depends only on 1.
4. Changes to sync only persistent conns (only in my head - TODO)

        Let me know if you can apply (1) to -next before the
SCTP patchset (its patch 2+3), it does not collide with (2),
I think.
