Chapter 3 Configuring ipge and e1000 Driver Parameters 33
kstat Statistics
TABLE 3-3 describes the kstat transmit and receive parameters.
cap_10hdx Local interface half-duplex capability
0 = Not 10 Mbit/sec half-duplex capable
1 = 10 Mbit/sec half-duplex capable
cap_asm_pause Local interface flow control capability
0 = Not asymmetric pause capable
1 = Asymmetric pause (from the local device) capable
cap_pause Local interface flow control capability
0 = Not Symmetric pause capable
1 = Symmetric pause capable
TABLE 3-3 Transmit and Receive Parameters
Parameter Description
xcvr_inits Number of physical layer re-initializations incremented every time
you change link parameters using ndd.
rev_id Revision ID of the ipge 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.
When 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 for enabling
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.
