I just realized my patch description is incorrect.  I had called out
xtables_options_xfrm as the function I was fixing when it was actually
references to xtables_merge_options I was fixing in the patch.  From
what I can tell, all the way up to 1.4.10 xtables_merge_options only had
3 parameters in include/xtables.h.in.  It looks like things switch to
version 6 in 1.4.11 and then xtables_options_xfrm takes 4 parameters.

I will update the patch description and send out a new copy tomorrow.

Thanks,

Alex
