* continue the work on multiple Rx queues (Sara)
* add support for beacon storing
  used in low power states (Sara)
* cleanups (Rodrigo, Johannes)
* fix the LED behavior for iwldvm (Hubert)
* Use the regular firmware image of WoWLAN (Matti)
* fix 8000 devices for Big Endian machines (Johannes)
* more firmware debug hooks (Golan)
