wireless-drivers-next patches for 4.13

Browse Source 
New features and bug fixes to quite a few different drivers, but
 nothing really special standing out.
 
 What makes me happy that we have now more vendors actively
 contributing to upstream drivers. In this pull request we have patches
 from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I
 still have patches from Marvell and Quantenna pending in patchwork. Now
 that's something comparing to how things looked 11 years ago in Jeff
 Garzik's "State of the Union: Wireless" email:
 
 https://lkml.org/lkml/2006/1/5/671
 
 Major changes:
 
 wil6210
 
 * add low level RF sector interface via nl80211 vendor commands
 
 * add module parameter ftm_mode to load separate firmware for factory
   testing
 
 * support devices with different PCIe bar size
 
 * add support for PCIe D3hot in system suspend
 
 * remove ioctl interface which should not be in a wireless driver
 
 ath10k
 
 * go back to using dma_alloc_coherent() for firmware scratch memory
 
 * add per chain RSSI reporting
 
 brcmfmac
 
 * add support multi-scheduled scan
 
 * add scheduled scan support for specified BSSIDs
 
 * add support for brcm43430 revision 0
 
 wlcore
 
 * add wil1285 compatible
 
 rsi
 
 * add RS9113 USB support
 
 iwlwifi
 
 * FW API documentation improvements (for tools and htmldoc)
 
 * continuing work for the new A000 family
 
 * bump the maximum supported FW API to 31
 
 * improve the differentiation between 8000, 9000 and A000 families
