Merge tag 'wireless-drivers-next-for-davem-2019-04-18' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
wireless-drivers-next patches for 5.2

Nothing really special standing out this time, iwlwifi being the most
active driver.

Major changes:

iwlwifi

* send NO_DATA events so they can be captured in radiotap

* support for multiple BSSID

* support for some new FW API versions

* support new hardware

* debugfs cleanups by Greg-KH

qtnfmac

* allow each MAC to specify its own regulatory rules
====================
