      mac80211: split out chandef tracing macros · 5a32aff3
      Johannes Berg authored 
      Some new APIs will require tracing a chandef without
it being part of a channel context, so separate out
the tracing macros for that.

      cfg80211: check radar interface combinations · 11c4a075
      Simon Wunderlich authored 
      To ease further DFS development regarding interface combinations, use
the interface combinations structure to test for radar capabilities.
Drivers can specify which channel widths they support, and in which
modes. Right now only a single AP interface is allowed, but as the
DFS code evolves other combinations can be enabled.

      cfg80211: Allow use_mfp to be specified with the connect command · cee00a95
      Jouni Malinen authored 
      The NL80211_ATTR_USE_MFP attribute was originally added for
NL80211_CMD_ASSOCIATE, but it is actually as useful (if not even more
useful) with NL80211_CMD_CONNECT, so process that attribute with the
connect command, too.

      mac80211: add encrypt headroom to PERR frames · 8680451f
      Bob Copeland authored 
      Mesh PERR action frames are robust and thus may be encrypted, so add
proper head/tailroom to allow this.  Fixes this warning when operating
a Mesh STA on ath5k:

      mac80211: set NEED_TXPROCESSING for PERR frames · 9cbbffe2
      Bob Copeland authored 
      A user reported warnings in ath5k due to transmitting frames with no
rates set up.  The frames were Mesh PERR frames, and some debugging
showed an empty control block with just the vif pointer:

>  [  562.522682] XXX txinfo: 00000000: 00 00 00 00 00 00 00 00 00 00 00

Set the IEEE80211_TX_INTFL_NEED_TXPROCESSING flag to ensure that
rate control gets run before the frame is sent.

      nl80211: allow user-space to set address for P2P_DEVICE · 1c18f145
      Arend van Spriel authored 
      As per email discussion Jouni Malinen pointed out that:

"P2P message exchanges can be executed on the current operating channel
of any operation (both P2P and non-P2P station). These can be on 5 GHz
and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz).

As an example, it would be possible to receive a GO Negotiation Request
frame on a 5 GHz only radio and then to complete GO Negotiation on that
band. This can happen both when connected to a P2P group (through client
discoverability mechanism) and when connected to a legacy AP (assuming
the station receive Probe Request frame from full scan in the beginning
of P2P device discovery)."

This means that P2P messages can be sent over different radio devices.
However, these should use the same P2P device address so it should be
able to provision this from user-space. This patch adds a parameter for
this to struct vif_params which should only be used during creation of
the P2P device interface.

      {cfg,nl}80211: mesh power mode primitives and userspace access · 3b1c5a53
      Marco Porsch authored 
      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 · 9bdbf04d
      Marco Porsch authored 
      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.
