Netgear R8000 Support for 802.11r?

Hey there, I wonder if 802.11r Fast Roaming is supported by the Netgear R8000 with the Broadcom BCM43602 Wifi chip. I tried to set it up, but it won't work. The issue was already descirbe once on this forum: 802.11r not working properly - #14 by pmera However, nobody confirmed this predication;

Is that true? Or am I doing something wrong?
Thank you for your time!

I have no idea, it's possible that the driver does not support it.
I would try capturing using tcpdump in monitor mode on another device and seeing whether there are any 802.11r packets.
