Bug Description

After a fresh install of Ubuntu 16.04 I disabled consistent device naming with the following Grub parameters:

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

This worked and I got "eth0" and "wlan0" for the Atheros AR9271 Rev:1 (TP-Link TL-WN722N). However after installation of the latest updates (kernel 4.4.0-22-generic), the wifi device went back to "wlxa42bb0bddb61".
