Ashok Nagarajan 70c33eaae7 {nl,cfg,mac}80211: Allow user to see/configure HT protection mode
This patch introduces a new mesh configuration parameter "ht_opmode" and will
allow user to check the current HT protection mode selected. Users could
configure the protection mode by the command "iw mesh_iface set mesh_param
mesh_ht_protection_mode=2". The default protection mode of mesh is set to
non-HT mixed mode.

Ashok Nagarajan 5533513784 {nl,cfg,mac}80211: Implement RSSI threshold for mesh peering
Mesh peer links are established only if average rssi of the peer
candidate satisfies the threshold. This is not in 802.11s specification
but was requested by David Fulgham, an open80211s user. This is a way to avoid
marginal peer links with stations that are barely within range.

This patch adds a new mesh configuration parameter, mesh_rssi_threshold. This
feature is supported only for hardwares that report signal in dBm.

Chun-Yeow Yeoh 94f9065648 {nl,cfg,mac}80211: Add support of setting non-forwarding entity in Mesh
A mesh node that joins the mesh network is by default a forwarding entity. This patch allows
the mesh node to set as non-forwarding entity. Whenever dot11MeshForwarding is set to 0, the
mesh node can prevent itself from forwarding the traffic which is not destined to him.

Paul Gortmaker bc3b2d7fb9 net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules
These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

which will advertise this mesh node as being a mesh gate.
NL80211_HWMP_ROOTMODE must be set or this will do nothing.

Javier Cardona c93b5e717e nl80211: New notification to discover mesh peer candidates.
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.

Javier Cardona 15d5dda623 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.

Javier Cardona c80d545da3 mac80211: Let userspace enable and configure vendor specific path selection.
Userspace will now be allowed to toggle between the default path
selection algorithm (HWMP, implemented in the kernel), and a vendor
specific alternative.  Also in the same patch, allow userspace to add
information elements to mesh beacons.  This is accordance with the
Extensible Path Selection Framework specified in version 7.0 of the
802.11s draft.

Johannes Berg 29cbe68c51 cfg80211/mac80211: add mesh join/leave commands
Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.

Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.

We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.

In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.
