Chapter 4: Linux Base Driver for 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.
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.
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.
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
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
