hi

          Do open source mac support 802.11 K in main line kernel
source tree ? further does any one working on it ?

Thanks in anticipation

IIRC last I looked into this it seemd 802.11k is more of a device
requirement on affinity for reporting signal amongst other things.
At least for signal we already try to report stuff in dBm when we can,
the resolution guarantee would be up to the device. It should be
relatively easily to do the conversion to the 11k range but not
sure which devices are capable of ensuring the affinity at the moment.

I'm sure there is more to 11k than just signal measurement, what else
was on it that you are interested? Too lazy to check right now.

Yes you are right signal strength stats constitute major part of
802.11k but there are other feature like neighbour element report and
some other features are there which if implemented may help us in
taking roaming related decisions in open source mac. What do you say
?

Sure, patches are always welcomed.
