Comment 8 for bug 1585863

Shih-Yuan, I think it would make more sense to just modify wifi-Signal-on-the-wifi-device-when-its-supplicant-i.patch in place, rather than creating a patch to patch our patch. :)

But I've asked cyphermox to check what's happening here, since it seems odd that his change to src/supplicant-manager/nm-supplicant-interface.c would be entirely unneeded?
