This patch adds defines for data structures and length information for CAN XL (CAN with eXtended data Length) which can transfer up to 2048 byte inside a single frame. Notable changes from CAN FD: - the 11 bit arbitration field is now named 'priority' instead of 'can_id' (there are no 29 bit identifiers nor RTR frames anymore) - the data length needs a uint16 value to cover up to 2048 byte (the length element position is different to struct can[fd]_frame) - new fields (SDT, AF) and a SEC bit have been introduced - the virtual CAN interface identifier is not part if the CAN XL frame struct as this VCID value is stored in struct skbuff (analog to vlan id) Acked-by: Vincent Mailhol <mailhol.vincent@wanadoo.fr> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> Link: https://lore.kernel.org/all/20220912170725.120748-5-socketcan@hartkopp.net Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> |
