51     6.6 CAN FD (flexible data rate) driver support
375   Remark about CAN FD (flexible data rate) support:
377   Generally the handling of CAN FD is very similar to the formerly described
378   examples. The new CAN FD capable CAN controllers support two different
379   bitrates for the arbitration phase and the payload phase of the CAN FD frame

410   For details about the distinction of CAN and CAN FD capable devices and
413   The length of the two CAN(FD) frame structures define the maximum transfer
414   unit (MTU) of the CAN(FD) network interface and skbuff data length. Two

554   CAN FD support in CAN_RAW sockets can be enabled with a new socket option

1166   6.6 CAN FD (flexible data rate) driver support
1168   CAN FD capable CAN controllers support two different bitrates for the
1169   arbitration phase and the payload phase of the CAN FD frame. Therefore a
1170   second bit timing has to be specified in order to enable the CAN FD bitrate.
1172   Additionally CAN FD capable CAN controllers support up to 64 bytes of
1185   MTU = 72 (CANFD_MTU) => sizeof(struct canfd_frame) => CAN FD capable device
1188   N.B. CAN FD capable devices can also handle and send legacy CAN frames.
1190   When configuring CAN FD capable CAN controllers an additional 'data' bitrate
1191   has to be set. This bitrate for the data phase of the CAN FD frame has to be
1197   specified to enable the CAN FD mode in the CAN controller. This controller

1202   Therefore two CAN FD implementations have to be distinguished today:
1204   - ISO compliant:     The ISO 11898-1:2015 CAN FD implementation (default)
1205   - non-ISO compliant: The CAN FD implementation following the 2012 whitepaper
1207   Finally there are three types of CAN FD controllers:
1211   3. ISO/non-ISO CAN FD controllers (switchable, like the PEAK PCAN-USB FD)
1214   netlink and displayed by the 'ip' tool (controller option FD-NON-ISO).
1216   switchable CAN FD controllers only.
