Would a SAS device ever attempt to open a connection through a disabled port
along the path to another SAS device?
If the originator-side expander port could not receive the OPEN address frame,
the originator would timeout.
If the responder-side expander port could not forward the OPEN address frame, it
might be forwarded out the expander's "subtractive" port, resulting in an
OPEN_REJECT (WRONG DESTINATION) response.
Is this the expected behavior? What would be the expander's response if it did
not include a "subtractive" port.
