Merge tag 'iwlwifi-next-for-kalle-2015-08-04' of https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

* Deprecate -10.ucode
* Clean ups towards multiple Rx queues
* Add support for longer CMD IDs. This will be required by new
	firmwares since we are getting close to the u8 limit.
* bugfixes for the D0i3 power state
* Add basic support for FTM
* More random that doesn't really stand out
