From 15d5dda623139bbf6165030fc251bbd5798f4130 Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Thu, 7 Apr 2011 15:08:28 -0700 Subject: cfg80211/nl80211: Add userspace authentication flag to mesh setup During mesh setup, use NL80211_MESH_SETUP_USERSPACE_AUTH flag to create a secure mesh and route management frames to userspace. Also, NL80211_CMD_GET_WIPHY now returns a flag NL80211_SUPPORT_MESH_AUTH if the wiphy's mesh implementation supports routing of mesh auth frames to userspace. This is useful for forward compatibility between old kernels and new userspace tools. Signed-off-by: Javier Cardona Signed-off-by: Thomas Pedersen Signed-off-by: John W.
