[PATCH 00/14] TDLS support for nl80211 drivers

[Arik Nemtsov]

This series adds basic TDLS support for nl80211 based drivers.
It is based in part on patches by Kalyan C. Gaddam, cc-ed here.

Support is added for peer discovery and data path setup/teardown.
Currently not implemented: QoS/HT, peer PSM, peer U-APSD and channel
switching.

Kernel-mode support is added in a companion series.

The main change from the RFC series is the addition of a TDLS peer STA
before initiating setup. This allows the driver to drop/buffer frames
sent to the peer during link setup, as required by the specification.

Tested with wl12xx hardware, with a nl80211/mac80211 based driver.

  TDLS: process discovery requests and send discovery responses
  TDLS/nl80211: support receiving TDLS discovery response frames
  TDLS: support sending a teardown frame from usermode
  TDLS: support sending TDLS discovery requests
  TDLS: implement low-ack event for lost TDLS peers
  TDLS: collect peer capabilities and supp-rates during link setup
  TDLS: add peer as a STA during link setup
  TDLS: support mgmt-frame Tx for ctrl-iface operations
