-* @brief General Receive is deprecated and shall not be accessed from app code,
-*        as polling is not supported by Ethernet.
-*
-* @param[in] hdl: handle of Ethernet driver
-* @param[out] buf: buffer to preserve the received packet
-* @param[out] length: length of the received packet
-*
-* @note Before this function got invoked, the value of "length" should set by user, equals the size of buffer.
-*       After the function returned, the value of "length" means the real length of received data.
-* @note This API was exposed by accident, users should not use this API in their applications.
-*       Ethernet driver is interrupt driven, and doesn't support polling mode.
-*       Instead, users should register input callback with ``esp_eth_update_input_path``.
-*
-* @return
-*       - ESP_OK: receive frame buffer successfully
-*       - ESP_ERR_INVALID_ARG: receive frame buffer failed because of some invalid argument
-*       - ESP_ERR_INVALID_SIZE: input buffer size is not enough to hold the incoming data.
-*                               in this case, value of returned "length" indicates the real size of incoming data.
-*       - ESP_FAIL: receive frame buffer failed because some other error occurred
