10GigEthr-03 (iocxgbe) B.11.31.1209 Ethernet Driver Release Notes, Edition 3

• Multi-queue operation is not available on all functions.
Severity: Medium
Multi-queue enables traffic to be partitioned across CPUs. The CNA supports only receive
multi-queue operation. Multiple queues are supported only on the first PCIe function for each
port: function 0 (port 0) and function 1 (port 1). The iocxgbe driver sets the number of receive
queues for each of these PCIe functions to 5. For each remaining PCIe function, the number
of queues is 1 and remains 1.
• Improper system shutdown results in a PCI error when iocxgbe devices are allocated to
guests in a DIO environment.
Severity: Low
In a DIO environment, shutting down the system improperly might result in a PCI error if
iocxgbe devices are allocated to a guest.
Workaround: To avoid this problem, shut down guests before shutting down or rebooting the
system. Follow the recommended HP-UX system shutdown and reboot procedures described
in the appropriate HP-UX administrator guide.
