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

For Gigabit Ethernet, HP-UX 11i v2 supplies the GigEther-00, GigEther-01, and IEther-00 driver bundles, which supply the gelan, igelan, and iether drivers, respectively.

Summary of Change

The May 2005 release of HP-UX 11i v2 include the following changes:

The igelan and iether drivers are now at version B.11.23.0505. The gelan driver remains at version B.11.23.05.
Introductory HP-UX release of the following new networking cards:
- AB290A PCI-X 2-Port U320 SCSI / 2-Port 1000Base-T Adapter (supported by the iether and mpt drivers)^[9]
- AB465A PCI-X Multifunction 2-Port 2Gb FC / 2-Port 1000Base-T Adapter (supported by the igelan and fcd drivers)^[10]
- 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 <ppa>
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 <ppa>
lanadmin -X recv_cko_on <ppa>
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.

Support of 1000FD mode of switches:

HP-UX 1000Base-T ports will support a link partner (switch or end-station) that is operating in 1000FD fixed/manual mode. Please ensure that your setting is one of the following supported configurations:

Table 4-2 HP-UX 1000Base-T Supported Configurations

HP-UX 1000Base-T Port	Link Partner	Resulting Speed
AUTO	AUTO	Highest Common Speed (HP-UX supports 10/100/1000)
AUTO	1000 FD fixed/manual	1000 Mbit/s FD
10 HD	10 HD (for example, a 10Base-T Hub)	10 Mbit/s HD
10 FD	10 FD	10 Mbit/s FD
100 HD	100 HD	100 Mbit/s HD
100 FD	100 FD	100 Mbit/s FD

Impact

With the Gigabit Ethernet drivers updated for this release, CKO settings can be set to what they used to be prior to this release 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 <ppa>

lanadmin -X recv_cko_on <ppa>

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.
