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 11)).
3 Problems fixed in this release The following defects were fixed in this release: Table 3 HP-UX 11i v3 June 2013 fixes — 10GigEthr-02 B.11.31.1306 SR number QXCR1001266661 Description After upgrading Virtual Connect (VC) firmware, the iexgbe Flex-10 interface goes to a DEAD state (driver state) While upgrading VC firmware, the iexgbe Flex-10 interface is reset. Because of a driver defect, the interface goes into the DEAD state but the link status remains UP (it should be DOWN).
Problems fixed in recent releases Table 4 HP-UX 11i v3 March 2013 fixes — 10GigEthr-02 B.11.31.1303.01 SR number QXCR1001270195 Description iexgbe 1303 versions introduced issues due to missing firmware lock The following symptoms might be seen because of this defect: • (QXCR1001268673) iexgbe driver continuously sends UP/DOWN notification events to the WBEM provider. The WBEM events seen by the user are of these types: DL_HP_EXT_LINK_DOWN_IND and DL_HP_EXT_LINK_UP_IND.
Table 5 HP-UX 11i v3 January/March 2013 fixes — 10GigEthr-02 B.11.31.1301 and B.11.31.1303 (continued) SR number Description queues supported. In such cases for drivers with versions AR1209 and earlier, the port transitions to the DEAD state. To make the port usable, a system reboot is required. The issue is rarely reproducible; reproducing the issue requires the above-mentioned stress testing sustained over a long duration. Table 6 HP-UX 11i v3 September 2012 fixes — 10GigEthr-02 B.11.31.
Workaround: Resolve the problem by resetting the link. Statistics will then be collected and updated properly. • 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”.
