Protected Management Frames 802.11w

Have poked around but have not discovered any current information about 802.11w implementation for the R7000.  I flashed my R7000 with the Nov 2017 version of Kong, but did not find any setting for enabling PMF.  Not sure if this is a chipset issie or if it is simply not implemented by this distribution.  I have a wannabe hacker in my neighborhood and they are doing periodic de-auth attacks which is killing my Nighthawk connections.   My other AP is an ASUS running Merlin release of DD-WRT, and it has 802.11w implemented on that one.  Anybody have any information about this topic as it pertains to the R7000?
