Hirschmann Hellcreek TSN industrial Ethernet switch
A Time-Sensitive Networking (TSN) Ethernet switch IP from Hirschmann (Belden), used in industrial and embedded systems where deterministic, low-latency networking matters. The publicly documented target is the hellcreek-de1soc-r1 evaluation platform, pointing to a narrow industrial/embedded footprint rather than consumer hardware.
recommendation
It should stay because the driver is still actively maintained upstream, with functional work landing as recently as November 2025 (HSR offload helpers in net-next), and Hirschmann/Belden continues to market TSN-capable industrial switches in the same product family. Deployments appear to be low-volume embedded and industrial rather than broad, but there is no replacement driver for the same hardware, so removing it would strand existing users.

As of 2025-11-30 the driver still receives net-next functional work ('use simple HSR offload helpers'), indicating active upstream maintenance rather than removal.

LKDDb shows CONFIG_NET_DSA_HIRSCHMANN_HELLCREEK is still present through 6.19-rc+HEAD and maps to compatible string 'hirschmann,hellcreek-de1soc-r1' and module 'hellcreek_sw'.
- git.zx2c4.com
The DT binding describes Hellcreek as a TSN switch IP and publicly documents only the 'hirschmann,hellcreek-de1soc-r1' compatible, suggesting a narrow embedded/eval-board style footprint.
- belden.com
Belden/Hirschmann was still marketing TSN-capable Hirschmann switch product lines in 2025-era web content, supporting ongoing industrial/TSN niche relevance for the vendor ecosystem even if not direct proof of new Hellcreek sales.

Belden's BOBCAT page shows current Hirschmann managed TSN-capable industrial switches remain on sale, reinforcing that the surrounding deployment niche is still alive.
codex reasoning notes (technical)
Not a removal candidate. `lore_file_timeline` on `drivers/net/dsa/hirschmann/hellcreek.c` showed steady activity from 2020 through 2025, including late-2025 feature work, and no removal signal surfaced before tool budget ran out. `rg` on local sources plus the LKDDb page and DT-binding URL indicate this driver targets the specific Hellcreek TSN switch IP / `hellcreek-de1soc-r1` platform, not a broad consumer NIC family. Belden web-search results show Hirschmann still sells TSN-capable industrial switches, so the use case remains relevant, but I found no direct 2025 sales evidence for Hellcreek itself; that points to low-volume embedded/industrial deployments rather than broad new sales. No natural replacement driver exists for the same hardware, so recommendation is keep.
