HFP/HSP hardware offload data path ID (default: 0).
This feature configures the SCO hardware‑offload data path for HFP/HSP using the Bluetooth
SIG–specified procedure. It is intended for advanced setups and vendor integrations. Do not
edit this unless required; incorrect values can disable SCO offload.
