Alacritech SLIC Mojave and Oasis gigabit Ethernet adapters

Alacritech's SLIC (Session Layer Interface Card) family of gigabit PCI Ethernet adapters from the 2000s, sold as TCP-offload "accelerator" NICs based on the Mojave and Oasis chipsets. They were marketed mainly to file-server and storage appliance vendors looking to lighten the host CPU's networking load.

recommendation

Worth keeping but flagging as legacy. The hardware is no longer sold and real-world deployments are presumed small, but the upstream code is not abandoned: maintainers landed a functional fix in 2024 and a statistics cleanup as recently as early 2026, so removing it would strand the remaining installed base for no real gain. An annotation noting its niche, end-of-life status would help future cleanup decisions.

sources

  1. lore.kernel.org

    Recent upstream activity exists: a 2026 net-next maintenance patch updated slicoss statistics handling.

  2. lore.kernel.org

    The driver still received a 2024 functional fix/revert, indicating occasional real maintenance rather than complete abandonment.

  3. git.kernel.org

    Upstream Kconfig describes this as support for Alacritech SLIC Gigabit Ethernet adapters, specifically Mojave and Oasis PCI cards.

codex reasoning notes (technical)

lore_file_timeline on drivers/net/ethernet/alacritech/slicoss.c showed touches through 2026-01-22 and a small but real maintenance stream, with no removal evidence surfaced in the checked lore history. Local source inspection (exec_command) identified the hardware family as Alacritech SLIC Mojave/Oasis gigabit PCI adapters; the kernel.org Kconfig URL is cited via canonical recall for that product description. A follow-up removal search via lore_regex timed out, and lei was blocked by the sandbox, so absence of removal discussion is only weakly supported. Overall read: hardware appears legacy and likely limited to installed-base use, but upstream still accepts fixes, so deprecate/remove would be premature; annotate as legacy instead.
