First of all, thanks for your performance analysis and patches. I'm
very inclined of merging them.
It seems that with current compilers and CFLAGS, the code from
ip_packet_match() is very bad, using lot of mispredicted conditional branches I made some patches and generated code on i386 and x86_64
is much better.
This only describes your "compare_if_lstrings()" changes, and I'm happy
to merge them.
However, you also removed the use of the FWINV macro and replaced it by
explicit code (including the bool1/bool2 variables, which are not really
named intuitively). Why was this neccessary?
