Code Releases Activity

Lots of updates for net-next; along with the usual flurry 

of small fixes, cleanups and internal features we have:
  * VHT support for TDLS and IBSS (conditional on drivers though)
  * first TX performance improvements (the biggest will come later)
  * many suspend/resume (race) fixes
  * name_assign_type support from Tom Gundersen
