Detailed Description

nRF71 Wi-Fi driver coexistence transport API.

The nRF71 is a single-die Wi-Fi + Short-Range (BLE) combo SoC. Coexistence between the two radios is arbitrated on-chip by the Coexistence Controller (COEXC) hardware and a Coexistence Manager (CM) that runs in the RPU/LMAC firmware.

Commands from the host-side Coexistence Driver (CD) to the CM are carried over the Wi-Fi FMAC host<->RPU control path, which is owned by this Wi-Fi driver. This header exposes a small, stable transport so the coexistence driver (drivers/nrf71_sr_coex) does not need to reach into the Wi-Fi driver's private FMAC context.
