During the CAN FD standardization process within the ISO it turned out that the failure detection capability has to be improved. The CAN in Automation organization (CiA) defined the already implemented CAN FD controllers as 'non-ISO' and the upcoming improved CAN FD controllers as 'ISO' compliant. See at http://www.can-cia.com/index.php?id=1937 Finally there will be three types of CAN FD controllers in the future: 1. ISO compliant (fixed) 2. non-ISO compliant (fixed, like the M_CAN IP v3.0.1 in m_can.c) 3. ISO/non-ISO CAN FD controllers (switchable, like the PEAK USB FD) So the current M_CAN driver for the M_CAN IP v3.0.1 has to expose its non-ISO implementation by setting the CAN_CTRLMODE_FD_NON_ISO ctrlmode at startup. As this bit cannot be switched at configuration time CAN_CTRLMODE_FD_NON_ISO must not be set in ctrlmode_supported of the current M_CAN driver.

Most CAN controllers have a support for ignoring ACK absence. Some of them refer to this feature as a self test mode (e. g. SJA1000) and some include it as a part of a loopback mode (e. g. MCP2510). Setting the introduced flag via netlink should make CAN controller perform a successful transmission, even if there is no acknowledgement (dominant ACK bit) received.

Armin pointed me to the fact that the identifier which is used to ensure the unique include processing in lunux/include/uapi/linux/can.h is CAN_H. This clashed with his own source as includes from libraries and APIs should use an underscore '_' at the identifier start. This patch fixes the protection identifiers in all CAN relavant includes.

The configuration for CAN FD depends on CAN_CTRLMODE_FD enabled in the driver
specific ctrlmode_supported capabilities.
The configuration can be done either with the 'fd { on | off }' option in the
'ip' tool from iproute2 or by setting the CAN netdevice MTU to CAN_MTU (16) or
to CANFD_MTU (72).

As CAN FD offers a second bitrate for the data section of the CAN frame the infrastructure for storing and configuring this second bitrate is introduced. Improved the readability of the if-statement by inserting some newlines.
