GigEther-00, GigEther-01, and IEther-00 (Gigabit Ethernet)

For Gigabit Ethernet, HP-UX 11i v1 supplies the GigEther-00, GigEther-01, and

IEther-00 driver bundles, which supply the gelan, igelan, and iether drivers,

respectively.

NOTE A list of systems that use the three currently supported Gigabit Ethernet drivers is

located in the HP-UX Ethernet Driver Support Matrix, Edition 2 (for the September 2004

release and later) at http://docs.hp.com under “Networking and Communications”

and then under “Gigabit Ethernet”.

Summary of Change

The September 2005 release of HP-UX 11i v1 includes the following changes:

•The GigEther-01 (igelan) driver has been updated to version B.11.11.20. The

IEther-00 (iether) driver has been updated to version B.11.11.09. The gelan driver

has not been updated.

• HP-UX 11i v1 now supports the following new networking cards:

— AB290A PCI-X 2-Port U320 SCSI / 2-Port 1000Base-T Adapter (supported by the

iether and mpt drivers)

— AB465A PCI-X Multifunction 2-Port 2Gb FC / 2-Port 1000Base-T Adapter

(supported by the igelan and fcd drivers)

— AB545A PCI-X 4-Port 1000Base-T Adapter (supported by the iether driver)

• Checksum Offload (CKO) changes for the iether and igelan Gigabit Ethernet

drivers:

These Gigabit Ethernet drivers now allow customers to turn the CKO feature of the

Gigabit Ethernet interface ON or OFF. With this and subsequent versions of the

iether and igelan drivers, the default for receive-side CKO will be OFF (disabled).

The current CKO settings can be determined with the following command:

lanadmin -x cko

If desired, the previous settings can be restored with the new driver by using the

lanadmin -X command. The exact lanadmin commands are as follows (note that the

X is capitalized in these commands):

lanadmin -X send_cko_on

lanadmin -X recv_cko_on

Example settings for the iether driver:

The settings are preserved across reboots by setting both

HP_IETHER_SEND_CKO

and

HP_IETHER_RECV_CKO

to ON or OFF in the /etc/rc.config.d/hpietherconf file.
