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
TABLE 4-11
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 4-12
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 towards link partner capability
lp_cap_pause
0 = Not symmetric pause capable
1 = Symmetric pause capable
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.
