[support] XFRM

[Jakub "Arkon" Syrek]

Hi
I know that it may not be proper list but I am looking at xfrm.c source of 
mipl + nemo/MCoA support ..
I'm trying to figure out how setting XFRM in mipl  works but i can't.
I was googling all day today but found nothing about it.
I've found that xfrm_mip_policy_add() create some policy for packet by try 
to fit it to selector (ip, port, type etc.) but what xfrm_state_add() do? 
What happens than with this selected packet?
Can someone explain it to me, please?

Regards
