Subject: testing checksum in helpers is redundant with tcp_window_tracking

Would it not be a good idea to have some kind of macro defined when
tcp_window_tracking in built into netfilter so that all of the helpers
and other code that are doing things like TCP checksum verification
and whatnot, can avoid wasting cycles doing it a second time?
Then helpers could wrap their tcp checksum calls with something like:
#ifndef TCP_WINDOW_TRACKING
...
#endif
Or is a runtime check a better idea? If so what test could be done at
runtime to know that tcp_window_tracking is checking TCP checksums?
