[B.A.T.M.A.N.] [PATCHv3 0/3] Implement the AP-Isolation mechanism

This is the third version of the AP-Isolation patchset. The patches have been rebased on top of the master branch but they have been left mostly unmodified.

The Ap-isolation mechanism will prevent (if enabled) WIFI clients to communicate with other WIFI clients over the mesh network. WIFI check on a client is done by default while the isolation is performed only if the mechanism is enabled either on the receiver and on the transmitter side.

Ap-isolation can be enabled or disabled by means of a new sysfs attribute (a batctl patch has also been provided to toggle interact with it).

Thank you all.

Regards, Antonio Quartulli
