ethtool

Ethtool is a Linux net driver diagnostic and tuning tool for the Linux 2.4.x (or later) series of kernels. The software offers users access to a wealth of information and diagnostics related to media, link status, driver version, PCI (or other) bus location, and more. This makes it the go-to tool for IT professionals and network administrators who are looking for a way to diagnose and fine-tune their network configurations.

This latest release of Ethtool offers several new features and improvements over previous versions. For example, it fixes handling of statistics where the label is exactly 32 bytes. It also adds the ability to change the advertised speed/duplex to a different range of values, rather than all-or-one. Additionally, it adds/updates register dump support for ixgb, sky2, Fabric7 VIOC, e1000, r8169, and SMSC LAN911x/LAN921x.

Furthermore, the software now has the ability to decode raw register dump stored in a file, as well as force hex register dump. Additional 10Gbps support is included, and 2.5G support is included. Finally, the internal ethtool.h has been synchronized with upstream kernel 2.6.23-rc1.

Overall, this latest release of Ethtool is a great choice for anyone in need of a reliable and feature-rich diagnostic and tuning tool for their Linux network. It's easy to use, and offers a wide range of features that make it an essential tool for anyone who needs to keep their network running smoothly.
