the pfkey / xfrm interface throws them away

i fixed racoon to send the port numbers and they were ignored

IIRC I tested port selectors in SA a few years ago using "ip xfrm"
and they worked fine. The xfrm interface doesn't ignore them 
(copy_from_user_state()), I think the pfkey interface also doesn't.

Please try configuring them manually using "ip xfrm state",
I'm pretty sure the bug is actually in racoon.
