About:
Libnl is a suite of libraries providing APIs to the Linux kernel's netlink interface. It simplifies the complex task of configuring and managing networking subsystems like routing, sockets, and traffic control. This library is essential for developers building network management tools that need to communicate directly with the kernel.

Key Features:

Object-based API for netlink sockets
Support for routing, neighbor tables, and traffic control (QoS)
High-level interface for network configuration
Command-line utilities for network inspection and control

Use Cases:

Developing network management applications
Configuring routing tables and IP addresses programmatically
Monitoring network interface states and statistics

Alternatives:

iproute2 – iproute2 provides the standard 'ip' command-line tool, while libnl offers a C library for programmatic access to the same kernel interfaces.
