IBM Retires 10Gb Ethernet Driver for Outdated POWER Hardware
IBM is retiring a 10Gb Ethernet driver from the mainline Linux kernel, scheduled for removal in the upcoming Linux 7.3 kernel. This driver represents one of the earliest implementations of 10Gb Ethernet technology. Its retirement is seen as unsurprising given the ongoing process of removing older hardware support from the Linux kernel, similar to how PCMCIA and ISA drivers are phased out. The decision reflects the natural evolution of technology, where older interfaces and hardware become obsolete and are no longer maintained in the primary codebase. This move signifies a broader trend of kernel developers focusing on modern hardware and faster interfaces, while gradually deprecating support for legacy systems. The retirement of this specific driver highlights the long lifespan some components can have within the kernel before eventually being superseded by newer, more efficient technologies. It is expected to be removed in 2026.
The retirement of legacy hardware drivers, such as IBM's 10Gb Ethernet driver for POWER hardware, is a predictable outcome of technological advancement and kernel maintenance cycles. As computing power increases and new standards emerge, older interfaces become less relevant and more costly to maintain. This process allows kernel developers to streamline the codebase, improve performance, and focus resources on supporting modern hardware and emerging technologies like AI-driven systems. The decision reflects a natural market dynamic where innovation necessitates the phasing out of outdated infrastructure. While this move may require users of legacy POWER systems to plan for hardware upgrades or alternative support solutions, it ultimately contributes to a more efficient and forward-looking computing ecosystem.
