Bug 427020

SUMMARY
I have two computers running openSUSE. One uses networkmanager, and ksysguard widgets show network stats just fine; the other uses wickedd (an openSUSE creation; I need that on that other computer because otherwise NIS and autofs would start way too late), and on that one the ksysguard network monitor does not show any statistics.
Plasma on both machines is from the openSUSE Build service repos

STEPS TO REPRODUCE
1. Install Leap 15.2
2. Add the Plasma Repositories from build.opensuse.org
3. Update "everything" to get plasma to 5.19.90
4. Set up a network monitor widget showing upload and download rate
5. Observe: when networkmanager is used for the network the monitoring works; when wickedd is, it does not.

OBSERVED RESULT
While wickedd is managing the network the traffic is not "seen"

EXPECTED RESULT
Traffic is monitored no matter which tool is managing the network connections
