Subject: [PATCH] asus-grouper: create nonfree firmware subpackage (!252)

With this firmware I can connect to my AP using wpa_supplicant, ping
servers and fetch files normally. However the driver also brings up the
p2p0 interface on boot and it seems to conflict with wlan0. So to test
the wireless we need to disable p2p0 and stop the wpa_supplicant service
(because it attaches itself to p2p0 on boot):

$ sudo ip link set p2p0 down
$ sudo rc-service wpa_supplicant stop
$ wpa_passphrase <your ESSID> <your password> > ./wpa_config
$ sudo wpa_supplicant -B -Dnl80211 -iwlan0 -c./wpa_config
$ sudo udhcpc -i wlan0
$ ping postmarketos.org
