LiteX LiteEth FPGA soft Ethernet MAC
LiteEth is an Ethernet MAC implemented in FPGA logic rather than as a standalone chip. It is part of the open-source LiteX ecosystem used to build custom system-on-chip designs (often paired with RISC-V or other soft CPU cores) on FPGA boards, and provides basic 10/100/1000 Mbps networking for those bespoke designs.
recommendation
Worth keeping but documenting its niche because LiteEth is not a chip you buy off the shelf; it is an Ethernet MAC implemented as soft IP inside FPGA designs built with the open-source LiteX framework. The kernel code received real maintenance fixes in 2023 and a substantive update in January 2024, and the upstream LiteEth project is still actively developed, so it serves a small but live community of FPGA and RISC-V SoC builders.

LiteEth is still listed in the active LiteX cores ecosystem as supported Ethernet hardware/IP for multiple FPGA families.
codex reasoning notes (technical)
Kernel source inspection via shell showed a real platform net driver for the LiteX LiteEth soft MAC. `git -c safe.directory=... log -- drivers/net/ethernet/litex` found ongoing upstream touches through 2024 and exposed lore URLs for the 2023 and 2024 maintenance patches; no removal-oriented commits or discussion appeared in that history. Web search found the active LiteEth upstream repo and LiteX ecosystem wiki, which show current ecosystem presence, but this is niche FPGA soft-IP rather than mass-market standalone hardware. Recommendation is keep-annotate: maintained and still relevant for new FPGA-based deployments, but low-volume and specialized.
