While playing with "IO-less dirty throttling v7" patcheset I did fall
in some few cases in a WLAN connection which was not setup at startup.

I guess all trouble is due to fast parallelization (especially
systemd) and the non-existence of the socket-file.

The relevant part (until - do -done ) was removed in functions.sh
while upgrade 0.6.x -> 0.7.x:
...
-       until [ -S "$WPA_CTRL_DIR/$WPA_IFACE" ]; do
-               if [ "$WPA_SOCKET_WAIT" -ge "$MAX_WPA_SOCKET_WAIT" ]; then
-                       wpa_msg stderr "ctrl_interface socket not
found at $WPA_CTRL_DIR/$WPA_IFACE"
-                       return 1
-               else
-                       wpa_msg verbose "waiting for
\"$WPA_CTRL_DIR/$WPA_IFACE\": " \
-                               "$WPA_SOCKET_WAIT (max. $MAX_WPA_SOCKET_WAIT)"
-               fi
-
-               WPA_SOCKET_WAIT=$(($WPA_SOCKET_WAIT + 1))
-               sleep 1
-       done
...

To summarize... all my efforts do not really work reliable at startup.
So, please fix this soon.

Thanks in advance.
