Yes. I will correct the patch description in updated version.

Mix of wildcard and specific MAC addresses were observed even for single external registrar case. This patch makes sure that AuthorizedMACs subelement prepared by an external registrar will contain either wildcard MAC or specific MAC addresses.

I assume that AP can still include both wildcard and specific MAC addresses if multiple external registrars are present.

Please correct me if I am missing something.
