This file describes the Linux* Base Driver for the Intel(R) PRO/1000 Family
of Adapters, version 4.4.x. This driver includes support for
of Adapters, version 5.0.x. This driver includes support for
Itanium(TM)-based systems.
This release version includes the following:
- Support for the ethtool 1.6 interface. A third-party application can use
the ethtool interface to get and set driver parameters.
- Zero copy. This feature provides faster data throughput. Enabled by
default in supporting kernels. It is not supported on the Intel(R)
PRO/1000 Gigabit Server Adapter.
Features include:
- Support for the 82545 and 82546-based adapters listed below
- Wake on LAN* support via ethtool for 82540, 82544, 82545, and 82546-
based adapters
- Adaptive IFS for increased performance at half duplex
Native VLANs are now available with supported kernels.

To verify your Intel adapter is supported, find the board ID number on the
adapter. Look for a label that has a barcode and a number in the format of
123456-001 (six digits hyphen three digits). Match this to the list of
numbers above.
