/**

|
* @file rv_radio_ops.h
|
|
* @brief ADR-081 Layer 1 — Radio Abstraction Layer.
|
|
*
|
|
* A single function-pointer vtable (rv_radio_ops_t) that isolates chipset
|
|
* specific capture details from the layers above (adaptive controller, mesh
|
|
* plane, feature extraction, Rust handoff).
|
|
*
|
|
* Two bindings ship today:
|
|
* - rv_radio_ops_esp32.c — wraps csi_collector + esp_wifi_*
|
|
* - rv_radio_ops_mock.c — wraps mock_csi.c (when CONFIG_CSI_MOCK_ENABLED)
|
|
*
|
|
* A third binding (Nexmon-patched Broadcom/Cypress) is reserved but not
|
|
* implemented here. The whole point of the vtable is that the controller
|
|
* and mesh-plane code above never need to know which one is active.
