--- Comment #12 from Gleb Smirnoff <glebius@FreeBSD.org> ---
Normally inp pointer is passed down to ipfw and if it is passed, the lookup is
avoided. So in the trace with tcp_respond the pointer was somehow lost and ipfw
looked up the same inpcb again.

I'll try to reproduce it first on 13 and if I can, then will check 14.
