> With inter-family transforms the inner mode differs from the outer mode.

> In particular, the functions xfrm4_extract_inut/xfrm6_extract_inut

> format stored in skb->cb.  This is then used by the inner mode input
> functions to modify the inner IP header.  In this way the input function
> no longer has to know about the outer address family.
