SAS initiator and expander ports transmit NOTIFY (E/S) primitives to SAS target 
ports, as described in SAS1.1 subclause 7.2.5.9.

Here are a few questions:

Is it permissible for a wide port to transmit a primitive on each physical link?

The primitive is transmitted after the link reset sequence is complete.  I don't 
see reception of this primitive covered in the SAS link layer description.  

Is there a confirmation that informs the application layer of detection of this 
primitive?

Are there any recommendations for transmission frequency (ie, how often does the 
target device expect to receive the primitive)?

Thanks,
Gil
