Broadcom BCA access-point Wi-Fi chipset support for brcmfmac
Vendor-specific glue inside the brcmfmac Wi-Fi driver that handles Broadcom's "BCA" family of FullMAC chipsets — the Wi-Fi silicon Broadcom sells into wireless routers, home gateways, and enterprise access points, including its current Wi-Fi 7 and upcoming Wi-Fi 8 AP product lines.
recommendation
Worth keeping but documenting its niche, because it is the vendor plugin inside the brcmfmac Wi-Fi stack that targets Broadcom's access-point silicon used in routers, residential gateways, and enterprise APs rather than the laptop and phone chips most users associate with brcmfmac. It was added by Broadcom engineers in late 2022 and was still receiving vendor work in early 2024, and Broadcom continues to ship new Wi-Fi 7 and Wi-Fi 8 AP platforms, so the code has a live hardware base even though end-user Linux deployments on this silicon are uncommon.

Broadcom announced and sampled a new enterprise Wi‑Fi access-point platform in February 2026, implying ongoing new deployments of Broadcom AP silicon beyond 2025.
codex reasoning notes (technical)
Local inspection shows this is a real loadable brcmfmac vendor plugin (`module_init` in `module.c`) described as for 'Broadcom AP chipsets'. Local `git log` shows introduction in Dec 2022 and substantive follow-up in Jan 2024, with no local sign of retirement. Source 1 URL came from the `Link:` trailer in `git show b1d94be570c2`; source 2 URL came from the `Link:` trailer in `git show edec42821911`; sources 3 and 4 were obtained by web search on Broadcom investor pages. Conclusion: niche but current hardware family, no natural in-tree replacement beyond core `brcmfmac`, so keep it but annotate as vendor-/AP-specific and low-deployment.
