Please read the archives of freebsd-net. This has been discussed many times. There are valid reasons for this, particularly the fact that 64-bit counters are much more expensive to update on 32-bit architectures. API breakage is also a problem. We're aware that 2^32 is way to small a limit for modern network counters, but fixing it isn't trivial on 32-bit hardware. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
