wireless-drivers-next patches for 4.21

Browse Source 
First set of patches for 4.21. Most notable here is support for
 Quantenna's QSR1000/QSR2000 chipsets and more flexible ways to provide
 nvram files for brcmfmac.
 
 Major changes:
 
 brcmfmac
 
 * add support for first trying to get a board specific nvram file
 
 * add support for getting nvram contents from EFI variables
 
 qtnfmac
 
 * use single PCIe driver for all platforms and rename
   Kconfig option CONFIG_QTNFMAC_PEARL_PCIE to CONFIG_QTNFMAC_PCIE
 
 * add support for QSR1000/QSR2000 (Topaz) family of chipsets
 
 ath10k
 
 * add support for WCN3990 firmware crash recovery
 
 * add firmware memory dump support for QCA4019
 
 wil6210
 
 * add firmware error recovery while in AP mode
 
 ath9k
 
 * remove experimental notice from dynack feature
 
 iwlwifi
 
 * PCI IDs for some new 9000-series cards
 
 * improve antenna usage on connection problems
 
 * new firmware debugging infrastructure
 
 * some more work on 802.11ax
 
 * improve support for multiple RF modules with 22000 devices
 
 cordic
 
 * move cordic macros and defines to a public header file
 
 * convert brcmsmac and b43 to fully use cordic library

802.11ac QSR10g (aka Pearl) and QSR1000/QSR2000 (aka Topaz)
FullMAC chipsets running over PCIe.
If you choose to build it as a module, two modules will be built:
qtnfmac.ko and qtnfmac_pearl_pcie.ko.
qtnfmac.ko and qtnfmac_pcie.ko.
