How does wpa_supplicant fit in the scheme?

layer 1. the daemon receives the event a new wlan interface is available
layer 2. the broker says it needs wpa_supplicant
layer 1. wpa_supplicant tells the interface is ready
layer 2. the broker says the interface needs dhcp
layer 3. dhcp_client is run

I think wpa_supplicant is somewhat special because it uses the same name
for the interface in different states.

Bye, Jörg.
