Packet Engines Hamachi and Yellowfin Gigabit Ethernet NICs
Late-1990s and early-2000s PCI gigabit Ethernet cards from Packet Engines, namely the Yellowfin G-NIC and the Hamachi GNIC-II (the latter also covering Symbios 53C885 variants). They were primarily deployed in Beowulf scientific computing clusters of that era and have been out of production for roughly two decades.
recommendation
Already on the path to removal: patches posted to the netdev and LKML lists in April 2026 propose deleting both the Hamachi and Yellowfin drivers along with the entire packetengines vendor directory, on the grounds that the hardware has been obsolete for over twenty years. Nobody is shipping these cards new in 2025, and the historical user base was niche cluster computing, so dropping them affects effectively no one running modern Linux.

LKDDb identifies YELLOWFIN as support for Packet Engines G-NIC PCI Gigabit Ethernet or Symbios 53C885, with historical help text tying it to Beowulf clusters rather than modern deployments.

Historical Yellowfin driver page describes support for Linux 2.0 through 2.5 and positions Yellowfin/Hamachi as late-1990s/early-2000s hardware.
codex reasoning notes (technical)
Local source inspection via exec_command showed two PCI gigabit NIC drivers: Hamachi GNIC-II and Yellowfin G-NIC/SYM53C885, both with 1997-2001 era provenance in comments/Kconfig. lore_file_timeline and lore_message (MCP) showed fresh 2026 netdev/lkml removal patches for both files; this active removal discussion escalates the recommendation from deprecate to remove. Web search/open yielded LKDDb and a historical Yellowfin page indicating old Beowulf-cluster-era deployment, with no evidence of current new sales. Because exact market sunset year is not well sourced from the retrieved material, last_widely_available_year is left null.
