From 0eace2f735da15d64c1806f61d11650615ddc52b Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Mon, 19 Aug 2013 16:10:21 -0700 Subject: [PATCH 2/5] mwifiex: do not create AP and P2P interfaces upon driver loading Bug 60747 - 1286:2044 [Microsoft Surface Pro] Marvell 88W8797 wifi show 3 interface under network https://bugzilla.kernel.org/show_bug.cgi?id=60747 This issue was also reported previously by OLPC and some folks from the community. There are 3 network interfaces with different types being created when mwifiex driver is loaded: 1. mlan0 (infra. STA) 2. uap0 (AP) 3. p2p0 (P2P_CLIENT) The Network Manager attempts to use all 3 interfaces above without filtering the managed interface type. As the result, 3 identical interfaces are displayed under network manager. If user happens to click on an entry under which its interface is uap0 or p2p0, the association will fail. Work around it by removing the creation of AP and P2P interfaces at driver loading time. These interfaces can be added with 'iw' or other applications manually when they are needed.
