Not all parameters passed to ctnetlink_parse_tuple() and
ctnetlink_exp_dump_tuple() match the enum type in the signatures of these
functions. Since this is intended change the argument type of to be an int
value.

Maybe that should be changed/fixed.

u32 is not int, it's unsigned int

Please see the previous discussion at
http://www.spinics.net/lists/netfilter-devel/msg47540.html

I would argue that an unsigned int is an int(eger) and considered it
an unnecessary detail for the commit message to be explicit. I can
change it if others deem it incorrect.

Cheers
