The only reason that I've been able to figure out for having the
skb->len test in those places is the preceding xfrm4_policy_check()
or xfrm6_policy_check() must be able to shrink the skb->len?

When I did the original transform stuff in other code circa 1995, I'd
envisioned IP length or link layer (PPP) length shrinking (removing
padding after block ciphers) -- and apparently this implementation
extended that concept to transport layer, too.

Personally, I'd prefer that a single test be placed in the appropriate
spot in the xfrm* functions, instead.  Anybody know where?
