* @details It will handle decode the opcode from RX buffer and based on the opcode it will search
* for registered handler. Handler is called once it is found.
*
* @param[in] p_rx_buf Pointer to input buffer.
* @param[in] rx_buf_len Size of p_rx_buf.
* @param[out] p_tx_buf Pointer to output buffer.
* @param[in,out] p_tx_buf_len \c in: size of \p p_tx_buf buffer.
* \c out: Length of valid data in \p p_tx_buf.
*
* @retval NRF_SUCCESS Handler success.
* @retval NRF_ERROR_NULL Handler failure. NULL pointer supplied.
* @retval NRF_ERROR_INVALID_LENGTH Handler failure. Incorrect buffer length.
* @retval NRF_ERROR_INVALID_PARAM Handler failure. Invalid operation type.
* @retval NRF_ERROR_NOT_SUPPORTED Handler failure. Opcode not supported.
