TIMEOUT expires, the associated command will be aborted. An INITIATOR RESPONSE TIMEOUT field value
of zero indicates that the SSP target port shall disable the timer. This value is enforced by the transport layer.
The default value of 7D0h, specifies a 2 second time period.
 Reject to Open Limit contains the minimum time in 10 µs increments that the target port shall wait to establish a
connection request with an initiator port on an I_T nexus after receiving an OPEN_REJECT (RETRY),
OPEN_REJECT (CONTINUE 0), or OPEN_REJECT (CONTINUE 1). This value may be rounded as defined in
SPC-4. A REJECT TO OPEN LIMIT field set to 0000h indicates that the minimum time is vendor specific. This
minimum time is enforced by the transport layer.
