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.
wpa_supplicant \
-M -c wpa_wired.conf -ilan0 -D wired \
-M -c wpa1.conf -iwlan* \
-M -c wpa2.conf
