Here is the text of the referenced editor’s note.

Editor’s Note 35: To better tolerate single-bit errors, it might be prudent to require SAS-2 phys

transmit IDENTIFY address frame 3 times rather than just once. Although the frame includes a

CRC, there is no NAK to cause retransmission if it fails - the entire link reset sequence must be

restarted if a bit error corrupts the IDENTIFY address frame. If it were transmitted 3 times, that

would not be necessary. 3 times would cover DFE error propagation between back-to-back

EOAF-SOAF (which should be allowed). After sending one IDENTIFY, must be immediately ready

to handle an incoming OPEN. Can stop sending additional IDENTIFYs if that happens (or keep

sending them - it shouldn’t matter to the recipient).

I would like this editor’s not removed from the draft standard. 

This note is in conflict with the SL_IR statemachine.

I have seen no proposal to change the link layer functionality as suggested by this note and,

until such a proposal is made I believe this does nothing but add confusion.
