A quick look at the source shows that they're 64-bit unsigned
counters, so (according to an equally quick back-of-the-envelope
calculation) each packet counter should be able to handle a few
dozen centuries' worth of the largest possible throughput of a
gigabit Ethernet. The byte counters, obviously, are good for a lot
less; around half a century is the limit.
