Merge tag 'iwlwifi-next-for-kalle-2015-01-22' of https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

* more work for new devices (4165 / 8260)
* cleanups / improvemnts in rate control
* fixes for TDLS
* major statistics work from Johannes - more to come
* improvements for the fw error dump infrastructure
* usual amount of small fixes here and there (scan, D0i3 etc...)
