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 12)).
3 Problems fixed in this release The following defects were fixed in this release: Table 3 HP-UX 11i v3 March 2014 fixes — 10GigEthr-02 B.11.31.1403.01 SR number QXCR1001328356 Description LRO may truncate/enlarge TCP frames causing TCP performance degradation. The software LRO algorithm may try to coalesce an additional packet which does not belong to the same TCP segment. This can causes packet discards. This is a rare scenario involving a specific traffic pattern having TCP timestamps and sacks options.
Problems fixed in recent releases Table 4 HP-UX 11i v3 March 2014 fixes — 10GigEthr-02 B.11.31.1403 SR number QXCR1001309103 Description IEXGBE: VPD (Serial Number) is not updated with olrad -R/-r After online replacement, thenwmgr does not display the VPD information of the newly replaced card but it continues to display the VPD of the old card. The resume operation is made to re-read the VPD content from the new card so that nwmgr can display the correct VPD information: 1.
Table 6 HP-UX 11i v3 June 2013 fixes — 10GigEthr-02 B.11.31.1306 (continued) SR number Description 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). The interface cannot exchange heartbeat packets. Because the link is still UP, Serviceguard does not detect the interface issue. This leads to a Serviceguard Transfer Of Control (TOC).
Table 8 HP-UX 11i v3 January/March 2013 fixes — 10GigEthr-02 B.11.31.1301 and B.11.31.1303 SR number QXCR1001233679 Description Link status is incorrectly reported for LAN ports connected to a switch or pass-through When LAN ports are connected to a switch or pass-through, the iexgbe driver might fail to detect a cable connect or disconnect. As a result, the LAN interface link status on the system side is incorrectly displayed by nwmgr and lanadmin.
systems with MC/Serviceguard might exhibit a system Transfer Of Control (TOC), thereby inhibiting Serviceguard recovery from a link outage or network connectivity problem. Severity: Medium Workaround: Resolve the problem by resetting the link. Statistics will then be collected and updated properly.
