From 93da9cc17c5ae8a751886fd4732db89ad5e9bdb9 Mon Sep 17 00:00:00 2001 From: "colin@cozybit.com" Date: Tue, 21 Oct 2008 12:03:48 -0700 Subject: Add nl80211 commands to get and set o11s mesh networking parameters The two new commands are NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS. There is a new attribute enum, NL80211_ATTR_MESH_PARAMS, which enumerates the various mesh configuration parameters. Moved struct mesh_config from mac80211/ieee80211_i.h to net/cfg80211.h. nl80211_get_mesh_params and nl80211_set_mesh_params unpack the netlink messages and ask the driver to get or set the configuration. This is done via two new function stubs, get_mesh_params and set_mesh_params, in struct cfg80211_ops. Signed-off-by: Colin McCabe Acked-by: Johannes Berg Signed-off-by: John W.
