TABLE 3-3describes the kstat transmit and receive parameters.

TABLE 3-3Transmit and Receive Parameters

Parameter	Description
xcvr_inits	Number of physical layer re-initializations incremented every time
	you change link parameters using ndd.
rev_id	Revision ID of the ipge 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.
	When 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 for enabling 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.
tx_queue1	Number of packets queued for transmission on the second
	hardware transmit queue.
