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.
