`systemd-udev` changes vif name to **rename4**.

For 1st VIF `wpa_seekurjr1.conf` content:
~~~
network={
ssid="SeekurJr1"
key_mgmt=NONE
}
~~~
Run wpa_supplicant:
sudo wpa_supplicant -Dnl80211 -iwlan0 -c wpa_seekurjr1.conf
sudo dhclient -r wlan0
sudo dhclient wlan0
For second VIF `wpa_seekurjr2.conf` content:
~~~
network={
ssid="SeekurJr"
key_mgmt=NONE
}
~~~
Run wpa_supplicant:
sudo wpa_supplicant -Dnl80211 -irename4 -c wpa_seekurjr2.conf
sudo dhclient -r rename4
sudo dhclient rename4
Independently which interface I'm starting first, second one fails:
nl80211: MLME command failed (auth): ret=-16 (Device or resource busy)
I expect that virtual interfaces on Atheros AR9485 are working and I will be
able to connect to 2 wifi APs simultaneously, e.g.
