From 581a8b0feeed8877aab3a8ca4c972419790cd07f Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Thu, 7 Apr 2011 15:08:27 -0700 Subject: nl80211: rename NL80211_MESH_SETUP_VENDOR_PATH_SEL_IE To NL80211_MESH_SETUP_IE. This reflects our ability to insert any ie into a mesh beacon, not simply path selection ies. Signed-off-by: Javier Cardona Signed-off-by: John W.

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.

Notify userspace when a beacon/presp is received from a suitable mesh peer candidate for whom no sta information exists. Userspace can then decide to create a sta info for the candidate. If userspace is not ready to authenticate the peer right away, it can create the sta info with the authenticated flag unset and set it later. Signed-off-by: Javier Cardona Signed-off-by: John W.
