30 Sun 10-Gigabit Ethernet PCI-X Adapter Installation and User’s Guide • December 2005
Tabledescribes the read-only ixge device capabilities.
TABLE3-6 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 controlcapability
0 = Not asymmetric pause capable
1 = Asymmetric pause (from the local device) capable
cap_pause Local interface flow controlcapability
0 = Not Symmetric pause capable
1 = Symmetric pause capable
TABLE3-6 Receive and TransmitParameters
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
recognitionof 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 entirepage of packets less than 256 bytes
each was droppedbecause the driver was unable to map a new
page to replaceit.
rx_hdr_pkts Number of packets receivedthat were less than 256 bytes.
rx_inits Number of packets received
rx_jumbo_pkts Number of jumbo packets received.
rx_len_mm Receive length errorcount.
rx_msgdup_fail Number of times driver failed to duplicate a packet on receipt.
rx_mtu_drops Numberof times an entire page of packets greater than 256 bytes
and less than 1514 each was droppedbecause the driver was
unable to map a new page to replace it.
rx_new_hdr_pgs Numberof pages that were filled with packets less than 256 bytes
that got replacedduring reception.
rx_new_mtu_pgs Number of pages that werefilled with packets greater than 256
bytes and less than 1514 that got replacedduring reception.
rx_new_nxt_pgs Number of pages that contained packets that weresplit across
pages that got replaced during reception.
