NetHub

NetHub bridges device-side Wi-Fi capability to a selected host-link backend.

The current solution targets Wi-Fi SoCs such as BL616 / BL618 / BL616CL / BL618DG.

Current Status

Item	Current status
Reference bring-up path	`SDIO`
USB data path	device-side `USB ECM` backend implemented
USB control transport	device-side `USB ACM` transport plumbing implemented
SPI	not implemented
USER virtual channel	currently end-to-end in-tree on `SDIO`
Low power	currently `BL618DG` only
ATModule dependency	optional example composition only; not a NetHub core dependency

SDIO is the current in-tree reference path.
USB device-side backend exists now and provides ECM + ACM.
SPI is still a stub.
nethub core exposes data-plane, control-path, and virtual-channel facades without directly depending on ATModule.
The optional ATModule + bflbwifid + bflbwifictrl flow is an example composition, not a hard requirement for NetHub data-path use cases.
