Kalle Valo says:

====================
wireless-drivers-next patches for 4.8

Major changes:

iwlwifi

* more work on the RX path for the 9000 device series
* some more dynamic queue allocation work
* SAR BIOS implementation
* some work on debugging capabilities
* added support for GCMP encryption
* data path rework in preparation for new HW
* some cleanup to remove transport dependency on mac80211
* support for MSIx in preparation for new HW
* lots of work in preparation for HW support (9000 and a000 series)

mwifiex

* implement get_tx_power and get_antenna cfg80211 operation callbacks

wl18xx

* add support for 64bit clock

rtl8xxxu

* aggregation support (optional for now)

Also wireless-drivers is merged to fix some conflicts.
