Arch Linux

Description:
When bringing a wireless WPA connection down using `netcfg down <conn>` associated wpa_supplicant process is left running.
This is due to the fact that the check at line 77 in /usr/lib/network/8021x:
[[ -e "$WPA_CTRL_DIR/$INTERFACE" ]] || return
is broken. WPA_CTRL_DIR is not set and so the script returns here and leaves the wpa_supplicant running.

Here's a naive solution that I use on my machine. Just set the path before running the test.
[[ -z $WPA_CTRL_DIR ]] && WPA_CTRL_DIR="/run/wpa_supplicant"

Additional info:
* package version(s)
netcfg 3.0-1
* config and/or log files etc.

/etc/wpa_supplicant.conf:
ctrl_interface=DIR=/run/wpa_supplicant GROUP=network
update_config=1
network={
ssid="vallvagen22"
psk=*****
}


Steps to reproduce:
I have a fresh install here so I guess just use current and connect to a wireless thingy with WPA auth.
