With 100MBit it took about 5 minutes to overflow the 32bit byte counters (too less for typical mrtg and Nyquist-Shannon sampling theorem in mind), with 1GBit it takes about 30 seconds. If you consider this appreciable... well :) > detect those wraps in userspace and deal with it as needed. Of course, it's usually enough time for a typical userspace application to get scheduled at least twice. regards Mario -- User sind wie ideale Gase - sie verteilen sich gleichmaessig ueber alle Platten - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
