Description

At home, ppp0 is active and throughput values are displayed for this interface. Then I suspend my computer, and go to work where my internet interface is wlan0 and there is no more active ppp0 interface. Though, the ppp0 netload plugin still displays "0.00 Kio" instead of showing "-" for these values, like it is after restarting the computer.

This is with xfce4-netload-plugin 1:1.2.4-0mx150+1 (on the MX 16.1, Debian Jessie based linux distro)
