Chapter 4: Linux Base Driver for the PRO/1000 Family of Adapters

Ethtool

The driver utilizes the Ethtool interface for driver configuration and diagnostics, as well

as displaying statistical information. Ethtool version 1.6 or later is required for this

functionality.

The latest release of Ethtool can be found at: http://sourceforge.net/projects/gkernel.

Enabling Wake on LAN* (WoL)

WoL is configured through the Ethtool utility. Ethtool is included with all versions of Red

Hat after Red Hat 7.2. For other Linux distributions, download and install Ethtool from

the following website: http://sourceforge.net/projects/gkernel.

For instructions on enabling WoL with Ethtool, refer to the website listed above.

WoL will be enabled on the system during the next shut down or reboot. For this driver

version, in order to enable WoL, the e1000 driver must be loaded prior to shutting down

or suspending the system.

NAPI

NAPI (Rx polling mode) is supported in the e1000 driver. NAPI is enabled or disabled

based on the configuration of the kernel. To override the default, use the following

compile-time flags.

To enable NAPI, compile the driver module, passing in a configuration option:

make CFLAGS_EXTRA=-DE1000_NAPI install

To disable NAPI, compile the driver module, passing in a configuration option:

make CFLAGS_EXTRA=-DE1000_NO_NAPI install

See http://www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.

NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support for a

more complete Ethtool feature set can be enabled by upgrading Ethtool to

Ethtool-1.8.1.

NOTE: Wake On LAN is only supported on port A for the following devices:

* Intel® PRO/1000 PT Dual Port Network Connection

* Intel® PRO/1000 PT Dual Port Server Connection

* Intel® PRO/1000 PT Dual Port Server Adapter

* Intel® PRO/1000 PF Dual Port Server Adapter

* Intel® PRO/1000 PT Quad Port Server Adapter
