Hello,

I'm trying to make different wifi roaming tests with the 802.11 
amandments 802.11k and 802.11r.
I use the intel wifi chipset Intel Corporation Centrino Ultimate-N 6300 
and two Aerohive Access Points AP141 (with both 802.11k and 802.11r 
enabled).
With using wpa_supplicant (Version 2.5) and wpa_cli (Version 2.5) I was 
able to connect and roam between the APs by entering the command "roam 
<mac>" and actually an 802.11r roam was performed. Therefore the nl80211 
and iwlwifi driver was used.
So fast roaming seems to work properly, but I faced troubles with Radio 
Resource Management (802.11k)

Transmitting the command "neighbor_rep_request" in wpa_cli failed. I 
checked to log files and found the following lines:

wlan0: Control interface command 'NEIGHBOR_REP_REQUEST'
RRM: No RRM in current connection.

and

RRM: Determining whether RRM can be used - device support: 0x0
RRM: Insufficient RRM support in driver - do not use RRM

Now my question would be how to enable RRM, maybe using the iw-command?
I could not find any documenation or examples according to RRM.
The tests were performed with Ubuntu and Linux Kernel 3.13.0-79.

I hope there is someone who can help me!
Thanks, Stefan Feirer
