P2P: Allow P2P functionality to be disabled per interface
By default, P2P is enabled globally for all virtual interfaces and this
makes wpa_supplicant include WSC and P2P IEs in Probe Request frames for
all scans even if this is for a non-P2P station connection to speed up
device discovery. If an interface is dedicated for non-P2P station mode
operations, it is now possible to disable addition of WSC and P2P IEs
into Probe Request frames with a per-interface p2p_disabled parameter.
This can be set either in the configuration file (p2p_disabled=1) or at
run time ("wpa_cli -i wlan0 set p2p_disabled 1"). Unlike the previous
mechanism ("wpa_cli p2p_set disabled 1"), the new parameter changes the
behavior only for the specified interface while other interfaces
continue to follow the global P2P enabled/disabled state.
