1 10GigEthr-02 overview The 10GigEthr-02 bundle contains the PCIe 10 Gigabit Ethernet iexgbe driver.
or LOM represents a single, wired connection to network hardware as follows: • In a Blade Virtual Connect environment, the NIC is configured in Flex-10 mode. Each port is logically divided into up to four individual network devices which share the total bandwidth of the network connection. For more information about HP Virtual Connect, see http://h18004.www1.hp.com/products/blades/ virtualconnect/index.html. • In other environments, the NIC is configured as a single network device per port.
• Multiple receive queues • Receive Side Scaling (RSS) with TCP and UDP • TCP segment reassembly in driver • Jumbo Frames • Multicast and Promiscuous mode • IPv6 • IEEE 802.
Firmware update completed Updated firmware will be active after a system reboot • Boot time reduced significantly for configurations requiring that multiple parameters be set (QXCR1001149267) The boot time configuration delay when multiple parameters are being set is now reduced significantly.
Table 1 10GigEthr-02 flow control and Jumbo Frames support matrix MTU Rx flow control Tx flow control 1500 (non-Flex-10 ports) ON/OFF ON/OFF Default setting during driver initialization before startup config parameters are applied will be: ON Default setting during driver initialization before startup configuration parameters are applied will be: ON 9000 (non-Flex-10 ports) OFF only. ON/OFF Default setting during driver NOTE: initialization before startup 1.
WARNING: For flex10 interface, the Tx flow control will be always on and the Rx flow control will be always off lan3 current values: New Transmit Flow Control = Off NOTE: The warning message incorrectly displays the Tx flow control state as Off when it should be On. This is a known issue (see “Known problems and limitations” (page 10)).
Table 5 HP-UX 11i v3 May 2012 Fixes — 10GigEthr-02 B.11.31.1205 SR number Description QXCR1001209171 AVIO: High outbound discards on HPVM guest with iexgbe interface. TCP connections (such as rlogin and telnet) from a remote system to the guest do not work and the guest hangs intermittently. QXCR1001182096 When packets with an invalid LLC, IP or TCP header length are sent through the HPVM guest igssn interface, the iexgbe driver will drop such packets.
4 Known problems and limitations The following problems and limitations are known to exist in version B.11.31.1303: • QXCR1001270195 — iexgbe 1303 versions introduced issues due to missing firmware lock The following symptoms might be seen because of this defect: ◦ iexgbe driver continuously sends UP/DOWN notification events to the WBEM provider. (QXCR1001268673) The WBEM events seen by the user are of these types: DL_HP_EXT_LINK_DOWN_IND and DL_HP_EXT_LINK_UP_IND.
• Incorrect warning message after attempt to turn off Tx flow control for a Flex-10 interface When an attempt is made to turn off Tx flow control for a Flex-10 interface, a warning message indicates correctly that Tx flow control always stays on for Flex-10 interfaces; however, the warning message displays the current value of Tx flow control as “Off” instead of “On”. Severity: Minor Workaround: Disregard the displayed state of Tx flow control.
When you use the ncweb or SMH interface to change the number of receive queues, an error message appears. Workaround: Use nwmgr instead of ncweb to change number of the queues. The command syntax is: nwmgr -s -A drv_mq= -c lan where The number of queues that you want to enable. Instance number of the LAN interface; for example, lan1.
