<para>A whitespace-separated list of hardware address of the currently connected wireless
LAN. Use full colon-, hyphen- or dot-delimited hexadecimal. See the example in
<varname>MACAddress=</varname>. This option may appear more than one, in which case the
lists are merged. If the empty string is assigned to this option, the list of BSSID defined
prior to this is reset.</para>
