Hi there,

the following series has been posted on this list initially by Tomasz Bursztyka
on 2013-09-09 as "RFC v1" (see his mail below). Unfortunately there has not been
any reaction at all. As I wanted to use this feature I rebased Tomasz' patches,
made some adjustments to the text that he added to wpa_supplicant/defconfig and
here is "RFC v2".

To be able to utilize wpa_supplicant's ACS under control of NetworkManager I
created an additional NetworkManager patch against version 1.0.8 that is going
to be sent as a reply to this mail.
