30 Sun 10-Gigabit Ethernet PCI-X Adapter Installation and User’s Guide • December 2005

Table describes the read-only ixge device capabilities.

TABLE 3-6 describes the kstat ixge:1 receive and transmit 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 3-6 Receive and Transmit Parameters

Parameter Description

lb_mode Copy of the Loopback mode the device is in, if any.

rev_id Revision ID of the 10-Gigabit Ethernet device useful for

recognition of device being used in the field.

rx_allocb_fail Number of times the driver failed to allocate OS receive buffer.

rx_hdr_drops Number of times an entire page of packets less than 256 bytes

each was dropped because the driver was unable to map a new

page to replace it.

rx_hdr_pkts Number of packets received that were less than 256 bytes.

rx_inits Number of packets received

rx_jumbo_pkts Number of jumbo packets received.

rx_len_mm Receive length error count.

rx_msgdup_fail Number of times driver failed to duplicate a packet on receipt.

rx_mtu_drops Number of times an entire page of packets greater than 256 bytes

and less than 1514 each was dropped because the driver was

unable to map a new page to replace it.

rx_new_hdr_pgs Number of pages that were filled with packets less than 256 bytes

that got replaced during reception.

rx_new_mtu_pgs Number of pages that were filled with packets greater than 256

bytes and less than 1514 that got replaced during reception.

rx_new_nxt_pgs Number of pages that contained packets that were split across

pages that got replaced during reception.
