{cfg,nl}80211: mesh power mode primitives and userspace access

2013-01-16T21:48:04+00:00

Add the nl80211_mesh_power_mode enumeration which holds possible
values for the mesh power mode. These modes are unknown, active,
light sleep and deep sleep.

Add power_mode entry to the mesh config structure to hold the
user-configured default mesh power mode. This value will be used
for new peer links.

Add the dot11MeshAwakeWindowDuration value to the mesh config.
The awake window is a duration in TU describing how long the STA
will stay awake after transmitting its beacon in PS mode.

Add access routines to:
 - get/set local link-specific power mode (STA)
 - get remote STA's link-specific power mode (STA)
 - get remote STA's non-peer power mode (STA)
 - get/set default mesh power mode (mesh config)
 - get/set mesh awake window duration (mesh config)

All config changes may be done at mesh runtime and take effect
immediately.

{cfg,nl,mac}80211: set beacon interval and DTIM period on mesh join

2013-01-16T21:44:04+00:00

Move the default mesh beacon interval and DTIM period to cfg80211
and make them accessible to nl80211. This enables setting both
values when joining an MBSS.

Previously the DTIM parameter was not set by mac80211 so the
driver's default value was used.

cfg80211: fix channel error on mesh join

2012-12-03T10:24:49+00:00

Fix an error on mesh join when no channel has been
explicitly set beforehand.

Also remove a double semicolon.

nl80211/cfg80211: support VHT channel configuration

2012-11-26T11:42:59+00:00

Change nl80211 to support specifying a VHT (or HT)
using the control channel frequency (as before) and
new attributes for the channel width and first and
second center frequency. The old channel type is of
course still supported for HT.

Also change the cfg80211 channel definition struct
to support these by adding the relevant fields to
it (and removing the _type field.)

This also adds new helper functions:
 - cfg80211_chandef_create to create a channel def
   struct given the control channel and channel type,
 - cfg80211_chandef_identical to check if two channel
   definitions are identical
 - cfg80211_chandef_compatible to check if the given
   channel definitions are compatible, and return the
   wider of the two

This isn't entirely complete, but that doesn't matter
until we have a driver using it. In particular, it's
missing
 - regulatory checks on the usable bandwidth (if that
   even makes sense)
 - regulatory TX power (database can't deal with it)
 - a proper channel compatibility calculation for the
   new channel types

cfg80211: pass a channel definition struct

2012-11-26T11:42:58+00:00

Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.

Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

cfg80211: add cfg80211 exported function tracing

Also add tracing to the API functions that drivers

cfg80211: add channel tracking for AP and mesh

2012-06-29T11:39:15+00:00

We need to know which channel is used by a running
AP and mesh for channel context accounting and
finding matching/active interface combination.

STA/IBSS have current_bss already which allows us
to check which channel a vif is tuned to.
Non-fixed channel IBSS can be handled with
additional changes.

Monitor mode is going to be handled differently.

{nl,cfg,mac}80211: implement dot11MeshHWMPconfirmationInterval

2012-06-18T11:55:15+00:00

As defined in section 13.10.9.3 Case D (802.11-2012), this
control variable is used to limit the mesh STA to send only
one PREQ to a root mesh STA within this interval of time
(in TUs). The default value for this variable is set to
2000 TUs. However, for current implementation, the maximum
configurable of dot11MeshHWMPconfirmationInterval is
restricted by dot11MeshHWMPactivePathTimeout.
