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?

Bug description:
Description: Ubuntu Yakkety Yak (development branch)
Release: 16.10
Packages:
libnm-glib-vpn1:amd64 1.2.2-0ubuntu2
libnm-glib4:amd64 1.2.2-0ubuntu2
libnm-util2:amd64 1.2.2-0ubuntu2
libnm0:amd64 1.2.2-0ubuntu2
network-manager 1.2.2-0ubuntu2
Reproduce steps:
1. Install fwts by `sudo apt-get install fwts`.
2. Run the suspend & resume stress test.
sudo fwts s3 --s3-multiple=30 --s3-min-delay=10 --s3-max-delay=10 --s3-delay-delta=5
Expected result:
The WiFi still functioned.
Actual result:
The WiFi can not connect to any access point and we have to execute `sudo wpa_cli scan` manually to make it work again.
P.S. Ubuntu 16.04 also has the same issue.
