I don't see anything in the SAS spec that specifies what the link layer
should do when an ERROR primitive is received within a frame.  I think its
implied that the ERROR is ignored, and the frame will fail the CRC check
and will be NAKed anyway.  It might be a good idea to include something
like: ERROR
ERROR is sent by an expander device when it is forwarding dwords from a SAS
or SATA link to a SAS link
and it receives an invalid dword.  << ERROR shall be ignored by initiator
ports and target ports. >>

Bye for now,
