No, but it may be helpful (neighbor report).

No, 802.11r is likely to use a different AP-to-AP protocol.

There are number of preliminary implementations, but I do not know
whether there are released product with 802.11r support.

Most of the needed code should be there, but currently, mac80211
requires couple of patches to allow user mode MLME support for client
mode since it does not yet had support for client side 802.11r
operations. AP side should be there.

I have not tested with the current mac80211 version, so I'm not sure
about the current state. Anyway, I would expect this to work with the
usermode patches from I hope to be
able to run more complete tests in the near future.
