10GigEthr-03 overview Bundle description The 10GigEthr-03 bundle contains the iocxgbe driver, which supports the following products: PCIe 10 GbE card PCIe 10GbE CNA / Fibre PCIe 10 GbE mezzanine card Channel Combo Cards PCIe 10 GbE CNA mezzanine cards AT118A NC552m AT094A NC551m AT111A NC553m Terminology When referring to CNA (Converged Network Adapter) technology, the following terms are used: Adapter The CNA. AVIO Accelerated Virtual Input/Output.
New and changed features in this release New features The following features are new with this version of 10GigEthr-03: • Direct I/O (DIO) support Direct IO networking gives the LAN device driver direct control of the device's IO. This minimizes device emulation overhead that would be incurred with accelerated virtual I/O (AVIO). In HP-UX vPars and Integrity VM environments, AVIO I/O devices are para-virtualized and do not allow the guest operating system to directly control the hardware.
B.11.31.1103.01 The following table lists defects reported and fixed in B.11.31.1103.01: SR number Column Head QXCR1001086347 Transmit requests with TSO enabled were very slow resulting in poor performance. QXCR1001092588 Interrupt migration could result in stuck interrupt status, causing an apparent device hang. QXCR1001085896 Multi-queue settings, specifically the range of the allowed number of queues, were confusing. B.11.31.1103 No defects were reported.
Hardware requirements This version of 10GigEthr-03 runs with the HP-UX 11i v3 (B.11.31) operating system on HP Integrity BL8x0c i2 server blades and the HP Integrity rx2800 i2 and Superdome 2 systems.
