This series implements the diag interface for the MPTCP sockets. Since the MPTCP protocol value can't be represented with the current diag uAPI, the first patch introduces an extended attribute allowing user-space to specify lager protocol values.
The token APIs are then extended to allow traversing the whole token container. Patch 3 carries the actual diag interface implementation, and later patch bring-in some functional self-tests.
