Intel 10 Gigabit Ethernet SR-IOV Virtual Function driver (ixgbevf)
The guest-side network driver for virtual functions exposed by Intel's 10 Gigabit Ethernet server adapters based on the 82599, X540, X550, and X552 controllers. It lets a virtual machine talk directly to a slice of the physical NIC via SR-IOV, giving near-native 10GbE throughput in virtualization-heavy enterprise and cloud environments from roughly 2009 onward.
recommendation
Worth keeping but worth flagging as a legacy-leaning enterprise driver. Intel still sells SR-IOV-capable parts like the X550-T2 in the 2025-2026 window and upstream development is genuinely active, with a major XDP/libeth feature series landing in March 2026 and a use-after-free fix in April 2026. At the same time, Intel has already ended support for the 82599 virtual function in its own release 30.6, so the supported hardware footprint is shrinking and documentation should make clear this is primarily a virtualization driver for older-to-midlife 10GbE silicon.

Netdev saw a substantial ixgbevf feature series in March 2026 ('libeth and full XDP for ixgbevf'), indicating active upstream development rather than removal.

Netdev carried an ixgbevf bug-fix patch in April 2026 for a use-after-free, showing current maintenance and real bug traffic.

Kernel documentation describes ixgbevf as the Linux VF driver for Intel 10GbE SR-IOV devices and lists 82599, X540, X550, and X552-based hardware support.
- edc.intel.com
Intel's adapter guide says release 30.6 ended support for Intel 82599 Virtual Function, showing at least part of the supported hardware family is legacy/EOL.
- intel.com
Intel's X550-T2 product page still showed 'Marketing Status: Launched' and SR-IOV capability, so some ixgbevf-capable underlying hardware remained commercially current in the 2025-2026 window.
codex reasoning notes (technical)
Real PCI net driver directory. Local source inspection via shell showed ixgbevf targets VF variants of 82599/X540/X550 families. Mailing-list evidence was obtained by web search because lore MCP/lei were unavailable here: spinics pages show both a major March 4, 2026 feature series and an April 13, 2026 bug fix, with no removal/deprecation thread found in those searches. Kernel docs URL was obtained by web search for supported hardware/use-case. Intel discontinued-support and X550 product URLs were obtained by web search to judge hardware age and continued new-sale status. Conclusion: keep upstream, but annotate as a legacy 10GbE SR-IOV guest driver with shrinking hardware scope (notably 82599 EOL) and mainly enterprise/virtualization deployments.
