Marvell AQtion AQC113/114/115/116 Multi-Gigabit Ethernet Controllers

Second-generation AQtion PCIe multi-gigabit Ethernet controllers (2.5/5/10 Gbps) — the AQC113, AQC114CS, AQC115C, and AQC116C chips originally from Aquantia before Marvell acquired it in 2019. They are commonly found on enthusiast motherboards, workstations, NAS appliances, and docking stations, and remain marketed for new designs in 2025.

recommendation

It should stay in the kernel because the hardware is still actively sold by Marvell in 2025 for PCs, workstations, NAS boxes, and docking stations, and the code is still receiving real bug fixes from contributors as recently as November 2025 (a descriptor cache fix) and June 2025 (a Wake-on-LAN fix). There is no sign of an upstream effort to retire it.

The atlantic PCI table routes AQC113/AQC114CS/AQC115C/AQC116C device IDs to hw_atl2_ops, confirming this directory is the hardware backend for those controllers.

codex reasoning notes (technical)

In-tree evidence gathered with shell (`sed`, `rg`, `git log -c safe.directory=...`) showed hw_atl2 backs AQC113/AQC114CS/AQC115C/AQC116C and has non-trivial fixes in 2024-2025, including two ATL2-specific/publicly linked patches above. Web search found Marvell product pages and product brief showing these controllers remained marketed for new designs in 2025-era materials. No removal discussion surfaced in reachable lore/web results; given ongoing fixes plus still-marketed silicon, `keep` is the defensible recommendation.
