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.

I get the following error in logread on Linksys EA9200 (also using BCM43602) when 802.11r is enabled:
ieee80211 phyX: brcmf_configure_wpaie: Invalid key mgmt info

Clients wlll not connect when 802.11r or 802.11k is active.

BTW, when enabling brcmfmac tracing (debug=4), I also see 28 times per minute
brcmfmac: brcmf_netdev_start_xmit phyX-ap0: insufficient headroom (0)

Again, I have no idea about brcmfmac

OK; I mostly wanted this information on the thread for people googling the error messages.
