Interesting.. I have not seen this in my tests, but maybe I have only
tested with different PROset versions.

OK. I would prefer this to be worked around in more visible way, i.e.,
something like (completely untested; hwaddr_aton_dots would be the new
function handling the incorrect format that was used by the ER).

val = xml_get_first_item(data, "NewWLANEventMAC");
if (val) {
	if (hwaddr_aton(val, macaddr)) {
	    wpa_printf(MSG_DEBUG, "WPS: Invalid NewWLANEventMAC '%s'",
	    if (hwaddr_aton_dots(val, macaddr)) {
		val = NULL;
	    } else
		wpa_printf(MSG_DEBUG, "WPS: Workaround - accepted "
			   "incorrect NewWLANEventMAC format");
if (val == NULL) {
