can: add ISO 15765-2:2016 transport protocol
CAN Transport Protocols offer support for segmented Point-to-Point communication between CAN nodes via two defined CAN Identifiers. As CAN frames can only transport a small amount of data bytes (max. 8 bytes for 'classic' CAN and max. 64 bytes for CAN FD) this segmentation is needed to transport longer PDUs as needed e.g. for vehicle diagnosis (UDS, ISO 14229) or IP-over-CAN traffic. This protocol driver implements data transfers according to ISO 15765-2:2016 for 'classic' CAN and CAN FD frame types.
