TABLE 4-12

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 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.

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.

rx_split_pkts

Number of packets that were split across two pages.

rx_no_comp_wb

Number of times the hardware cannot post completion entries for
received data.

rx_no_buf

Number of times the hardware cannot receive data because there is
no more receive buffer space.

rx_new_pages

Number of pages that got replaced during reception.
