10GigEthr-03 (iocxgbe) B.11.31.1203.02 Ethernet Driver Release Notes, Edition 2

Known problems and limitations
The following problems are known to exist in version B.11.31.1203.02:
• Problems occur when using SNAP (Sub-Network Access Protocol) encapsulation with VLANs.
(QXCR1001061473)
Severity: Medium
SNAP encapsulation enables protocols such as TCP/IP to use an IEEE802.3 SNAP header.
This protocol works correctly for non-VLAN devices. For VLAN devices, when a minimum size
SNAP packet is received and the VLAN tag is removed, the device incorrectly flags the packet
as undersized and discards it.
Workaround: None. This problem might be corrected in a future release of the 10GigEthr-03
bundle.
• 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.
