Intel PRO/1000 (8254x) Gigabit Ethernet adapters
Intel's first generation of PRO/1000 gigabit Ethernet controllers, the 82542 through 82547 family (including the popular 82540EM and 82545EM), shipped as PCI and PCI-X server and desktop NICs from roughly 2002 onward. Intel discontinued the line by 2014, but the chips remain extremely common as the default emulated NIC in virtual machines.
recommendation
Worth keeping but documenting its niche: the physical cards are obsolete and Intel finished discontinuing them in 2014, yet the driver still receives real bug-fix activity in mainline and remains the backing driver for the Intel PRO/1000 MT virtual NIC that VirtualBox, QEMU and other hypervisors expose to guests by default. That virtualization use case alone justifies continued maintenance, so a comment noting the legacy/VM-guest scope would help future maintainers without removing anything.

- docs.kernel.org
Upstream kernel documentation describes e1000 as the Intel PRO/1000 driver and explicitly references very old controllers such as 82542, 82543, 82544, 82547 and 82540/82545-era adapters.

LKDDb shows CONFIG_E1000 is still present in current kernels and maps the driver to many legacy Intel PCI PRO/1000 device IDs including 82542/82543/82544/82540/82545/82546/82547 variants.
- intel.com
Intel ARK lists the 82540EM as launched in Q3 2002 and discontinued, with expected discontinuance on May 13, 2014, supporting that this hardware family is long past new mainstream sales.
- virtualbox.org
Current VirtualBox documentation still offers Intel PRO/1000 MT Desktop (82540EM), T Server (82543GC), and MT Server (82545EM) virtual NIC models, showing ongoing VM-guest niche deployment.
codex reasoning notes (technical)
Local shell inspection (`rg`) shows this is real driver code and names old 8254x-era MACs; local shell `git -c safe.directory=... log --since=2021` shows recent nontrivial fixes through 2026-04-06, so it is maintained rather than abandoned. lore-http MCP was unavailable in this session, and web searches against lore.kernel.org for e1000 removal/deprecation terms did not surface an active removal series, so there is no visible removal signal here. URLs were obtained via `web.search_query`/`web.open`; the maintenance evidence came from local shell, not a URL. Recommendation is `keep-annotate`: hardware is obsolete and not meaningfully sold new in 2025, but the driver still gets bug-fix traffic and remains relevant for legacy systems plus virtualization niches.
