Calxeda Highbank XGMAC server Ethernet
Onboard 10/100/1000 Ethernet found on Calxeda's Highbank and Midway ARM server-on-chip systems, an early-2010s attempt to bring low-power ARM CPUs into the data center. The hardware shipped on a small number of niche microservers before Calxeda went out of business in late 2013.
recommendation
Worth keeping but flagging as obsolete: Calxeda folded in December 2013, the hardware was never widely deployed, and any remaining systems are essentially lab curiosities or collectors' boards. However, the driver still sees occasional upstream attention, including a real bug-fix in 2023 and a treewide API touch-up in 2024, so there is no active push to remove it and no reason to rush one.

- lore.kernel.org
The driver still received a targeted bug-fix patch in 2023, indicating some residual upstream maintenance rather than total abandonment.
- lore.kernel.org
The most recent 2024 touch was a treewide API-adjustment patch, not a removal discussion.

Upstream Kconfig still exposes CONFIG_NET_CALXEDA_XGMAC and ties it specifically to the Calxeda Highbank XGMAC device/module xgmac.
- wiki.ubuntu.com
Ubuntu's ARM server wiki describes Calxeda Midway and Highbank boards as commercially available before Calxeda's closure, showing these were niche early-2010s server platforms.
- techradar.com
Calxeda shut down in December 2013, strongly indicating the hardware family is long out of new production.
codex reasoning notes (technical)
Single-platform Ethernet driver for Calxeda Highbank/related ECX server SoCs, confirmed locally from Kconfig/of_match. lore_file_timeline on xgmac.c showed recent activity through 2024, but it is mostly treewide API churn; the cited 2023 lore patch is the clearest evidence of residual bug-fix traffic, while the 2024 lore patch shows no active removal series. Web search surfaced LKDDb for continued kernel presence, Ubuntu wiki pages showing the platform was an early-2010s niche ARM server product, and TechRadar reporting Calxeda's 2013 shutdown. Conclusion: hardware is obsolete and not sold new in 2025, deployments are likely only legacy/collector/lab use, but upstream attention is still nonzero, so keep the driver with obsolescence annotation rather than deprecate/remove.
