r8168dkms

The r8168dkms package provides a kernel module for Realtek 8168, 8169, and other compatible Gigabit Ethernet controllers. DKMS stands for Dynamic Kernel Module Support, a framework that allows kernel modules to be automatically rebuilt when the system's kernel is updated. This is particularly useful for proprietary or out-of-tree drivers, such as the r8168 driver, which may not be included in the mainline Linux kernel. Installing r8168dkms ensures that the network interface remains functional after kernel upgrades without manual intervention.

The r8168 driver itself is a high-performance driver for Realtek's Gigabit Ethernet network interface cards. It is often preferred over the generic r8169 driver included in the kernel for certain hardware revisions due to improved stability, performance, or feature support. Users typically install r8168dkms when they encounter issues with their Realtek network adapter using the default driver, or when specific features require this particular module. The package automates the process of compiling and installing the driver against the currently running kernel, simplifying system maintenance for users relying on this hardware.
