capset

Capset refers to a set of options that can be used to configure network interface parameters on a computer system. These parameters often control aspects of how the network card handles incoming and outgoing data. While the term "capset" itself might not be a universally recognized or standardized technical term across all operating systems and networking contexts, it generally implies a collection of settings related to network capabilities or capacities.

Commonly, capset configurations might involve adjusting buffer sizes, which dictate how much data can be temporarily stored by the network interface before being processed or transmitted. This can impact performance, especially under heavy network load. Other potential settings could relate to interrupt moderation, a technique that helps reduce CPU overhead by grouping network events, or specific hardware offloading features that allow the network card to perform certain tasks traditionally handled by the CPU.

The specific tools and methods for configuring these parameters vary significantly. On Linux-based systems, users might interact with such settings through command-line utilities like ethtool, which allows for detailed inspection and modification of network device driver parameters. In other environments, these configurations might be managed through graphical network configuration panels or system management interfaces. Understanding and adjusting capset parameters can be a technique for network administrators seeking to optimize performance or troubleshoot connectivity issues.
