>Description:
This patch fixes all outstanding issues with statistics of network
devices in ksysguardd (best described in KDE bug 61512).
It fixes KDE bug 61512 and the problems mentioned in KDE bug 47710.
This is my last PR in the "fixing ksysguardd series". If there
are any other problems left, I'm not aware of, please let me know.
