This implies that you always have some tp in hands. AFAIK this is not true,
so that I am puzzled how you were able to make something compilable with this definition.

At least in tcp_v4_send_ack() you obviously use some invalid tp, there is
no socket in hands there. The thing which is called "sk" is dummy.

With container migration I used per-container offset. When you have no container,
you have to do something a little bit smarter.
