On systems that have multiple WLAN rfkill instances, the rfkill code can become confused into thinking that the device was unblocked when in fact it wasn't, because it only matches on the WLAN type. Since it then stores the new (unblocked) state from the wrong rfkill instance, it will never retry the failing IFF_UP operation and the user has to toggle rfkill again, or otherwise intervene manually, in this case to get back to operational state. Fix this by using the existing (but unused) ifname argument when the rfkill instance is created to match to a specific rfkill index only. As a P2P Device interface does not have a netdev interface associated with it, use the name of a sibling interface to initialize the rfkill context for the P2P Device interface. For nl80211, as the wiphy index is known only after getting the driver capabilities from the kernel, move the initialization of the rfkill object to wpa_driver_nl80211_finish_drv_init().

This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
