From e057dd3fc20ffb3d7f150af46542a51b59b90127 Mon Sep 17 00:00:00 2001 From: Oliver Hartkopp Date: Mon, 28 Sep 2020 22:04:04 +0200 Subject: 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.
