Fujitsu FMV-J18x PCMCIA Ethernet cards

A family of 16-bit PCMCIA (PC Card) Ethernet adapters built around the Fujitsu MBH86960A and compatible chips, sold for laptops in the 1990s before USB and ExpressCard displaced the PC Card slot around 2003.

recommendation

Already on the path to removal: an April 2026 netdev patch series proposes deleting the driver outright, and the underlying PC Card bus has been obsolete for over two decades with no successor driver needed because anyone affected would simply replace the hardware. Residual deployments are minimal and the cards have not been sold new in many years.

sources

  1. lore.kernel.org

    An April 22, 2026 netdev patch series proposes deleting the fmvj18x driver entirely ('Remove this driver').

  2. cateee.net

    LKDDb identifies this as CONFIG_PCMCIA_FMVJ18X, a PCMCIA/PC-Card Ethernet driver producing module fmvj18x_cs.

  3. en.wikipedia.org

    PC Card/PCMCIA was superseded by ExpressCard in 2003 and most of its functionality moved to USB-era peripherals, indicating an obsolete deployment niche.

codex reasoning notes (technical)

Local inspection via exec_command showed the only driver is fmvj18x_cs.c and Kconfig labels it 'Fujitsu FMV-J18x PCMCIA support', so this is a 16-bit PCMCIA Ethernet driver for legacy laptops/cards. lore_file_timeline returned the cited 2026 netdev/lkml removal series URL, which is strong upstream evidence to escalate from deprecate to remove. Deployment evidence came from web search: LKDDb page confirms the exact driver scope, and the cited PC Card page shows the bus itself is long-obsolete and superseded; that supports 'still sold new in 2025 = false' and only low residual legacy deployments. No natural in-tree replacement driver covers the same specific hardware; users would replace the hardware/interface rather than switch drivers.
