+If the interfaces on which wpa_supplicant is to run are not known or do
+not exist, wpa_supplicant can match an interface when it arrives. Each
+matched interface is separated with -M argument and the -i argument now
+allows for pattern matching.
+
+As an example, the following command would start wpa_supplicant for a
+specific wired interface called lan0, any interface starting with wlan
+and lastly any other interface. Each match has its own configuration
+file, and for the wired interface a specific driver has also been given.

 If the interface is added in a Linux bridge (e.g., br0), the bridge
 interface needs to be configured to wpa_supplicant in addition to the
 main interface:
