Some time ago a REQUEST LENGTH field was added into the SMP functions. However, there was no way placed into SAS-2 to for an initiator to determine if an SMP device supports this SAS-2 request length field (verses the SAS 1.1 with a value of zero in that byte).

To resolve this I will be proposing a bit in the IDENTIFY address frame that will indicate if the SMP device supports a length field in the SMP function. Any comments?
