* Remark on CAN_ISOTP_DEFAULT_RECV_* values:
*
* We can strongly assume, that the Linux Kernel implementation of
* CAN_ISOTP is capable to run with BS=0, STmin=0 and WFTmax=0.
* But as we like to be able to behave as a commonly available ECU,
* these default settings can be changed via sockopts.
* For that reason the STmin value is intentionally _not_ checked for
* consistency and copied directly into the flow control (FC) frame.
