Here's a big pile of changes for this round. 

We have
  * a lot of regulatory code changes to deal with the
    way newer Intel devices handle this
  * a change to drop packets while disconnecting from
    an AP instead of trying to wait for them
  * a new attempt at improving the tailroom accounting
    to not kick in too much for performance reasons
  * improvements in wireless link statistics
  * many other small improvements and small fixes that
    didn't seem necessary for 3.19 (e.g. in hwsim which
    is testing only code)
