Chapter 4 Configuring Driver Parameters 41
If the link partner is not capable of autonegotiation (when lp_autoneg_cap is 0),the remaining information described in TABLE4-11 is not relevant and the parametervalue = 0.If the link partner is capable of autonegotiation (when lp_autoneg_cap is 1), thenthe speed and mode information is displayed when you use autonegotiation and thelink partner capabilities.TABLE4-12 describes the netstat -k transmit and receive parameters:
lp_cap_10hdx 0 = No 10 Mbit/sec half-duplex transmission
1 = 10 Mbit/sec half-duplex
lp_cap_asm_pause 0 = Not asymmetric pause capable
1 = Asymmetric pause towardslink partner capability
lp_cap_pause 0 = Not symmetric pause capable
1 = Symmetric pause capable
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.
