This series adds support for SAE authentication of mesh peers in userspace.  A
fork of wpa_supplicant that can authenticate mesh peers is available here:
https://github.com/cozybit/hostap-sae  .  Our intent is to work with hostap
maintainers to merge that functionality upstream soon.

A simpler daemon is also available here:  https://github.com/cozybit/authsae.

They both require the changes proposed in this series to operate.  Also, both
are based on the SAE reference implementation from Dan Harkins available here:
http://sourceforge.net/projects/authsae/

v2: (all suggested by Johannes)
 - Userspace actually creates the stations instead of setting the AUTH flag.
 - Fix hole that would allow peer links between secured and open peers.
 - Pass multiple IEs through generic IE nl80211 attribute
 - Remove SAE constant

v3: (again Johannes)
 - Fix API backward compatibilty of NL80211_MESH_SETUP_IE
 - Remove check for presence of RSN IE

v4: (also hinted by Johannes)
 - New peer event to avoid having to scan for mesh peer candidates
 - NEW_STATION command can also accept a PLINK_ACTION argument to
   trigger or block peer link establishment immediately after an authenticated
   station is created.

Javier Cardona (5):
  mac80211: Enable mesh security from userspace
  mac80211: Let user space receive and send mesh auth/deauth frames
  mac80211: Accept mesh auth frames before a peer link has been
    established
  mac80211: Let userspace create stations when mesh security is enabled
  mac80211: New notification to discover mesh peer candidates.
