Indicates whether the port is operating in
spantree fast start mode. A port with fast start
enabled is immediately put in spanning tree
forwarding state on link up, rather than starting
in blocking state which is the normal operation.
This is useful when the port is known to be
connected to a single station which has problems
waiting for the normal spanning tree operation to
put the port in forwarding state.
