Good question.
Based on the bit layout proposed in 07-091 for the SMP functions, I
think bit 4 should be the MSB and bit 7 should be the LSB.  That way, in
the SMP functions, it will have its natural encoding.
I suggest you post this Q&A to the T10 reflector to make sure nobody
else has assumed the opposite.

	Rob... 
	Can you clarify for me the bit ordering for the REQUESTED
LOGICAL LINK RATE in the SNW-3 settings? 
	The example uses "9", which is the same bit flipped or not. 
	Would be great to get a 1.5 example added to spec too since that
would show correct bit positions. 
	Thanks!
