When the target device gets rebooted, the counter values are reset to zero.
Need to detect the reboot events and wdc.data.api should calculate the bandwidth using the delta from zero. (Of course, the 1st bandwidth after reboot is not correct, but better than present any negative values.)

Currently, nwuCollect.sh polls ifInOctets/ifOutOctets, which are Counter32 and easily be circulated in high speed networks with long poll intervals.
Need to collect and calculate ifHCInOctets/ifHCOutOctets.
