802.11r not working

I have 8 "boxes" running the latest snapshot of OpenWrt.  7 of these are 
typical router boxes with WiFi hardware (Archer C7 v2, Archer A7 v5, 
Armor z2) and the remaining one is virtual and runs under KVM on a server.

I didn't think 802.11r was working so I ran a tcpdump on all 8 devices 
and it appears that my Samsung Galaxy S9 is sending the 802.11r ethernet 
890d frames to the MAC Address of the KVM based router, which as it has 
no WiFi hardware couldn't have been the original associating WiFi point 
and obviously isn't running hostapd.  Obviously no response is ever 
given to any of these packets as a consequence.

The KVM based router is running the radius server, does anybody have any 
thoughts on why this is happening?  I really don't understand why my 
phone is looking in the wrong place for a response!
