kstat Statistics

TABLE 3-3

describes the kstat transmit and receive parameters.

cap_10hdx

Local interface half-duplex capability
0 = Not 10 Mbit/sec half-duplex capable
1 = 10 Mbit/sec half-duplex capable

cap_asm_pause

Local interface flow control capability
0 = Not asymmetric pause capable
1 = Asymmetric pause (from the local device) capable

cap_pause

Local interface flow control capability
0 = Not Symmetric pause capable
1 = Symmetric pause capable

TABLE 3-3

Transmit 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.
