- * the CAN controllers bitstream processor into the CAN FD mode which creates
- * two new options within the CAN FD frame specification:
- *
- * Bit Rate Switch - to indicate a second bitrate is/was used for the payload
- * Error State Indicator - represents the error state of the transmitting node
- *
- * As the CANFD_ESI bit is internally generated by the transmitting CAN
- * controller only the CANFD_BRS bit is relevant for real CAN controllers when
- * building a CAN FD frame for transmission. Setting the CANFD_ESI bit can make
- * sense for virtual CAN interfaces to test applications with echoed frames.
