[src/trunk]: src/sys/netipsec Replace "cmp" of function names to "match" and ...
details: https://anonhg.NetBSD.org/src/rev/5d2394538620
branches: trunk
changeset: 353867:5d2394538620

description:
Replace "cmp" of function names to "match" and make their return value consistent
Function names with cmp are expected to return the order of two comparees
like memcmp and strcmp. The functions in question just answer if matched
or not, so don't use cmp and use match instead.
Consistently return 1 on matched and 0 otherwise.
