number of CPUs + 1 and hardware capability)

drv_pr_on Enable TCP Packet Reassembly in driver

drv_pr_off Disable TCP Packet Reassembly in driver

WARNING: The installed kernel modules include multiple versions of

the

module 'iocxgbe'. Version 1.0.[52DF621E] will be ignored.

* The requested changes have been applied to the currently

running configuration.

WARNING: The module 'iocxgbe' could not be set to the 'loaded' state,

because another module depends on it.

Module State Cause Notes

iocxgbe (before) unused loadable, unloadable

(now) loaded best

(next boot) loaded explicit

Workaround: If the above failure message is seen, explicitly run “/sbin/init.d/hpiocxgbe

start” to apply the intended settings in startup configuration file.

• After system boot, link problems are seen. For example, the link is DOWN and the speed is

1Gb/s; the link status should be UP with 10Gb/s (when connected to a 10Gb link). This

problem happens with the following adapters:

◦ NC553i Integrated (LOM) FlexFabric adapter

◦ NC552m (product number: 610609–B21)

◦ NC553m (product number: 613431–B21)

The problem is not caused by the iocxgbe driver. The problem is caused by a defect in the

firmware.

Severity: High

Workaround: Update to the latest firmware for the adapter. For more information, see

“Firmware requirements” (page 13).

• Firmware update fails for Emulex ATxxx adapters on HP-UX 1209.ic383 (QXCR1001255872)

Severity: Medium

When using the nwmgr to update firmware for Emulex ATxxx adapters, if the STRMSGSZ

tunable has a non-zero value, the update might fail. The error message will indicate an invalid

argument was detected.

Workaround: Use kctune to change the STRMSGSZ value to 0.

• 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
