Description: This object controls whether cut-thru is enabled on the stack. Enabling cut-thru can help to minimise the delay experienced by packets before they are forwarded to their destination. Setting cut-thru to 'fastForward' causes frame forwarding to begin as soon as 32 bytes of the frame have been received. Setting it to 'fragmentFree' causes frame forwarding to begin when 64 bytes have been received. This is slower, but eliminates the risk of forwarding an illegally short frame to the destination port, however a valid length frame might still be forwarded even though it had a CRC error. Setting this object to 'storeAndForward' disables cut-thru completely, and frames will not be forwarded until they have been received in their entirety.

Cut-thru cannot operate if the destination port is currently involved in 'cut-thru' from another port. In this case the device will process the frame in store and forward mode.
