Intel CSME/AMT-over-Wi-Fi bridge for iwlwifi (IWLMEI)
A communication channel that lets Intel's Management Engine firmware, the component behind vPro and Active Management Technology, share a Wi-Fi adapter with the host operating system on Tiger Lake and newer business laptops. It targets recent Intel wireless cards like the AX200/AX201 and enables remote out-of-band management to reach a machine over Wi-Fi rather than wired Ethernet.
recommendation
Worth keeping but its niche should be documented: Intel still ships vPro/AMT-capable Wi-Fi hardware in 2025 and the code is actively maintained, with bug fixes and SAP v4 protocol support landing in 2024-2025. However, the Kconfig option still depends on BROKEN and Intel itself states that wireless AMT is not validated on Linux, so real-world Linux deployment is very thin. No other in-tree driver provides the same CSME-over-WLAN handoff, so removing it would leave the function uncovered.

`CONFIG_IWLMEI` is a real tristate driver option for Intel Management Engine communication over WLAN; its help text says support starts from Tiger Lake platforms, was tested on 9260 devices only, and currently depends on `BROKEN`.
- git.kernel.org
The directory contains a real MEI client driver (`module_mei_cl_driver(iwl_mei_cl_driver)`) rather than only helper code.
- git.kernel.org
The directory has continued upstream maintenance through 2024-2025, including bug fixes and SAP version 4 support, which argues against removal for inactivity.
- intel.com
Intel was still marketing vPro manageability over wired or Wi-Fi in 2025-era materials, so the underlying enterprise hardware/use case remains current.
- intel.com
Intel's AMT materials describe wireless-capable Intel adapters on vPro platforms (example AX201), indicating the hardware class is not purely legacy.
- software.intel.com
Intel's wireless manageability guidance says Linux wireless AMT use is not validated, supporting a conclusion of niche/low Linux deployment despite ongoing hardware relevance.
codex reasoning notes (technical)
Real driver, confirmed by local shell inspection of `Kconfig` and `mei/main.c` in the kernel tree; local `git log` showed active 2024-2025 work (including SAP v4 support and fixes) and no evidence of an inactive/orphaned subtree. Kernel.org URLs are canonical recall corresponding to those locally inspected files/logs. Intel vPro/AMT URLs were obtained by web search and support that the hardware capability is still sold new, but Linux deployment appears low because `CONFIG_IWLMEI` is still `depends on BROKEN` and Intel's wireless AMT guidance says Linux wireless use is not validated. No natural in-tree replacement covers the same CSME-over-WLAN function.
