Sun Microsystems 806-2989-10 manual 12Transmit and Receive Parameters

TABLE 4-11

TABLE 4-11Read-Only Link Partner Capabilities (Continued)

Parameter	Description
lp_cap_10hdx	0	= No 10 Mbit/sec half-duplex transmission
	1	= 10 Mbit/sec half-duplex
lp_cap_asm_pause	0	= Not asymmetric pause capable
	1	= Asymmetric pause towards link partner capability
lp_cap_pause	0	= Not symmetric pause capable
	1	= Symmetric pause capable

If the link partner is not capable of autonegotiation (when lp_autoneg_cap is 0),

the remaining information described in is not relevant and the parameter value = 0.

If the link partner is capable of autonegotiation (when lp_autoneg_cap is 1), then the speed and mode information is displayed when you use autonegotiation and the link partner capabilities.

TABLE 4-12describes the netstat -k transmit and receive parameters:

TABLE 4-12Transmit and Receive Parameters

Parameter	Description
	Number of Physical layer re-initializations every time you change
xcvr_inits	link parameters using NDD this increments.
rev_id	Revision ID of the GigaSwift Ethernet device useful for recognition
	of device being used in the field.
xcvr_addr	GMII/MII Physical layer device address for management interface.
xcvr_id	GMII/MII Physical layer device Identification Decimal copy of MII
	registers 2 and 3.
lb_mode	Copy of the Loopback mode the device is in, if any.
qos_mode	When zero, the TX queues operate in a simple round robin
	queueing scheme, based on TCP/UDP destination port number. If
	set the TX queues operate in a scheme designed to provide VLAN
	priorities.
tx_starts	Number of times that the driver attempted to transmit a packet.

tx_dma_bind_fail Number of times a page table entry was not available to allow the driver to map the kernel memory to device accessible memory for

	transmission.
tx_queue0	Number of packets queued for transmission on the first hardware
	transmit queue.
