wpa_supplicant: Update to 29-Aug-2012 TOT
commit 6ffdc2f7bd496ace7a46e055f9714e7db4b1f722
Author: Jouni Malinen <jouni@qca.qualcomm.com>
Date: Fri Mar 2 22:31:04 2012 +0200
WFD: Add preliminary WSD request processing and response
This commit does not yet address support for different device roles,
i.e., the same set of subelements are returned regardless of which
role was indicated in the request.
