Subject: P2P2: Add support to fetch the P2P2 and PCC capability
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c144dcbdfbcf0e02d6f0e2040db0ab84f9460b68;p=thirdparty%2Fhostap.git

P2P2: Add support to fetch the P2P2 and PCC capability

Add support to fetch the P2P2 and PCC capability from wpa_supplicant.
This defines the driver capability bits for this and the control
interface extension. The actual driver capability fetching will be
handled in future commit(s).
