The DTFD (Disable Target Fabric Discovery) bit is used to force targets to only
support private loop behavior even if there is a fabric present on the loop. The
DTFD bit of 1 indicates that a target attached by an FC-AL loop shall not
recognize the presence of a fabric loop, FL_Port, on the loop. The target shall
perform only the private loop functions defined for targets defined by FC-PLDA.
The DTFD bit of 0 indicates that the target attached by an FC-AL loop shall
discover FL_Port if present on the loop and perform the public loop functions
defined for targets by FC-FLA.
The PLPB (Prevent Loop Port Bypass) bit is used to control whether or not the
controller ignore any Loop Port Bypass(LPB) / Enable(LPE) primitive sequences.
The PLPB bit of 0 indicate that the controller does not ignore any LPB / LPE.
The PLPB bit of 1 indicate that the controller ignore any LPB /LPE.
The DDIS (Disable Discovery) bit is used to control whether or not the controller
should wait for the authentication (i.e., ADISC or PDISC) to resume the tasks
which suspended by the loop initialization. The DDIS bit of 0 indicate that the
controller should wait the authentication. The DDIS bit of 1 indicate that the
controller does not wait the authentication.
