Hi Mathieu,
I found this issue on ath9k.
04:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless
Network Adapter [168c:0036] (rev 01)
Subsystem: Dell QCA9565 / AR9565 Wireless Network Adapter [1028:020e]
This patch is just back to the original implementation of the upstream.
Removing wifi-Signal-on-the-wifi-device-when-its-supplicant-i.patch can also
fix this issue.
BTW, I can also reproduce this issue on my own USB WiFi adapter.
Bus 003 Device 003: ID 07b8:3072 AboCom Systems Inc 802.11n/b/g Mini Wireless
LAN USB2.0 Adapter
Driver=rt2800usb (Ralink RT2800 USB Wireless LAN driver.)
** Patch added: "network-manager_1.2.2-0ubuntu4.debdiff"

Reproduce steps:

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.
