From 98104fdeda63d57631c9f89e90a7b83b58fcee40 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 16 Jun 2012 00:19:54 +0200 Subject: cfg80211: add P2P Device abstraction In order to support using a different MAC address for the P2P Device address we must first have a P2P Device abstraction that can be assigned a MAC address. This abstraction will also be useful to support offloading P2P operations to the device, e.g. periodic listen for discoverability. Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command. As it has no associated netdev, a P2P Device can only be identified by its wdev identifier but the previous patches allowed using the wdev identifier in various APIs, e.g. remain-on-channel.
