- handle ETH_P_CAN and ETH_P_CANFD skbuffs - update sanity checks for CAN and CAN FD - make sure the CAN frame can pass the selected CAN netdevice on send - bump core version and abi version to indicate the new CAN FD support Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
