Sun Microsystems Gigabit Ethernet MMF/UTP Adapter manual 3 Operational Mode Parameters Continued

TABLE 4-3Operational Mode Parameters (Continued)

Parameter	Description
MaxFrameSize	Upper limit on the maximum MTU size the driver allows.
	All Intel gigabit adapters (except the 82542-based Intel
	PRO/1000 adapter) allow the configuration of jumbo
	frames.
	The maximum MTU accepted by the MAC is 16128. Use
	ifconfig(1M) to configure jumbo frames. Use ifconfig
	with the adapter instance and the MTU argument
	(ifconfig e1000g0 mtu 16128) configures adapter
	e1000g0 for the maximum allowable jumbo frame size.
	Allowed values are:
	0	= Standard frames with an MTU of 1500. (default)
	1	= Jumbo frames with a maximum MTU of 4096.
	2	= Jumbo frames with a maximum MTU of 8192.
	3	= Jumbo frames with a maximum MTU of 16384.
FlowControl	Flow control utilizes Ethernet XON and unicast and
	multicast XOFF packets to allow Ethernet equipment to
	slow down the stream of data between two Ethernet
	devices.
	Allowed values are:
	0 = Disable. Packets can get dropped in high- throughput
	situations, leading to reduced network performance.
	1	= Receive only.
	2	= Transmit only.
	3	= Receive and transmit. (default).
	4	= Use adapter’s EEPROM-programmed factory default
	setting.
TbiCompatibilityEnable	You must enable this feature on Intel 82543CG-based
	copper adapters to operate correctly with TBI mode
	ethernet hardware.
	Allowed values are:
	0	= Disable.
	1	= Enable. (default).
SetMasterSlave	Controls the PHY master/slave setting. Manually forcing
	master or slave can reduce time needed to link with Planex
	08TX and IO data switches. This setting should remain as
	the hardware default.
	Allowed values are:
	0	= Hardware default. (default).
	1	= Force master.
	2	= Force slave.
	3	= Force auto.
