From f1a613118ed51f3ecbaab8940744f4ff205c2e67 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 3 Oct 2014 22:50:21 +0300 Subject: [PATCH] P2P: Use only the -m config for P2P management device Previously, the case of non-netdev P2P management device ended up pulling in both the main interface (e.g., wlan0) and P2P Device interface (from command line -m argument) as configuration. Similarly, the main interface ended up included both configuration files. This is not really helpful for various use cases, e.g., when permanent P2P group information is stored in the P2P Devince interface, but it gets duplicated in the main station interface configuration. Clean this up by changing the -m argument to replace, not concatenate, configuration information. In other words, the main station interface will not read this configuration and the P2P Device interface (non-netdev) does not read parameters from the station interface configuration file.
