Anyway, I have a fix which just throws away any samples where an overflow, correct or bogus, occurs. That is definitely fine in 64-bit land. Even at full speed, a 1GBit NIC would overflow only after >5000 years. Nothing that I worry about much :-) Even 5 years for a future 1Tbit NIC is not that bad... But in 32-bit, a 1Gbit NIC could overflow every 40 seconds. And that is very short.
