Hi,
I'm a little bit bothered because of those inner_ functions, what
about the following approach:
1. the skb will have a new state, that state can be outer (normal
mode) and inner.
2. when you change the state to inner, all the helper functions such
as ip_hdr will return the innter header.

that's ofcourse the API side. the implementation may still use the
fields you added to the skb.

what you think?
