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. > also, /(1024*1024.0) would give me my mb yeah?? Right.
