TABLE4-12 describes the netstat -k transmit and receive parameters:
TABLE4-12 Transmit and Receive Parameters
Parameter Description
xcvr_inits Number of Physical layer re-initializationsevery 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 addressfor management interface.
xcvr_id GMII/MII Physical layer device IdentificationDecimal copy of MII
registers2 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 roundrobin
queueing scheme, based on TCP/UDP destination port number.If
set the TX queues operate in a scheme designed to provideVLAN
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
hardwaretransmit queue.
tx_queue2 Number of packets queued for Transmissionon the third hardware
transmit queue.
tx_queue3 Number of packets queued for Transmissionon the fourth
hardwaretransmit queue.
tx_max_pend Maximum number of transmits pending on any of the four queues.
rx_hdr_pkts Number of packets receivedthat were less than 256 bytes.
rx_mtu_pkts Number of packets receivedthat were greater than 256 bytes and
less than 1514 bytes.
rx_split_pkts Number of packets that weresplit across two pages.
rx_no_comp_wb Number of times the hardwarecannot post completion entries for
receiveddata.
rx_no_buf Number of times the hardwarecannot receive data because there is
no morereceive buffer space.
rx_new_pages Number of pages that got replacedduring reception.
