56 Sun GigaSwift Ethernet Adapter Installation and User’s Guide • August 2004
If the link partner is not capable of autonegotiation (when lp_autoneg_cap is 0),
the remaining information described in
TABLE 4-12 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 4-13 describes the netstat -k transmit and receive parameters:
TABLE 4-13 Transmit and Receive Parameters
Parameter Description
xcvr_inits Number of physical layer re-initializations every time you change
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 enable 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.
tx_queue2 Number of packets queued for transmission on the third hardware
transmit queue.
tx_queue3 Number of packets queued for transmission on the fourth hardware
transmit queue.
tx_max_pend Maximum number of transmits pending on any of the four queues.
rx_hdr_pkts Number of packets received that were less than 256 bytes.
rx_mtu_pkts Number of packets received that were greater than 256 bytes and
less than 1514 bytes.
