Table 3: LPFC.conf Parameters (Continued)

Property Name	Scope	Default	Min	Max	Dynamic	Comments
topology	Controller	0x0	0x0=loop , then		No	This variable controls the FC
	Specific		P2P			topology expected by LPFC at
			0x2=P2P only			boot time. FC offers point-to-
			0x4=loop only			point, fabric, and arbitrated
			0x6=P2P, then			loop topologies.To make the
			loop			HBA operate as an N_Port,
						select point-to-point mode
						(used for N_Port to F_Port,
						and N_Port to N_Port
						connections). To make the
						HBA operate in a FC loop as
						an NL_Port, select loop mode
						(used for private loop and
						public loop topologies). The
						driver will reject an attempt to
						set the topology to a value not
						in the above list. The auto-
						topology settings 0 and 6 will
						not work unless the HBA is
						using firmware version 3.20 or
						higher.
use-adisc	Controller	0	0=Off	1=On	Yes	This variable controls the ELS
	Specific					command used for address
						authentication during re-
						discovery upon link-up. If set,
						ADISC is used, otherwise,
						PLOGI is used. For FCP-2
						devices, the driver will always
						use ADISC. For re-discovery
						due to a RSCN, the driver will
						always use ADISC.
xmt-que-size	Controller	256	128	10,240	No	This variable specifies the
	Specific					number of network packets
						that can be queued or
						outstanding at any time in the
						driver. Increase this setting for
						better IP performance under
						heavy loading.
