can: isotp: TX-path: ensure that CAN frame flags are initialized
The previous patch ensures that the TX flags (struct can_isotp_ll_options::tx_flags) are 0 for classic CAN frames or a user configured value for CAN-FD frames. This patch sets the CAN frames flags unconditionally to the ISO-TP TX flags, so that they are initialized to a proper value. Otherwise when running "candump -x" on a classical CAN ISO-TP stream shows wrongly set "B" and "E" flags. | $ candump any,0:0,#FFFFFFFF -extA | [...] | can0 TX B E 713 [8] 2B 0A 0B 0C 0D 0E 0F 00 | can0 TX B E 713 [8] 2C 01 02 03 04 05 06 07 | can0 TX B E 713 [8] 2D 08 09 0A 0B 0C 0D 0E | can0 TX B E 713 [8] 2E 0F 00 01 02 03 04 05 Fixes: e057dd3f ("can: add ISO 15765-2:2016 transport protocol") Link: https://lore.kernel.org/r/20210218215434.1708249-2-mkl@pengutronix.de Cc: Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by:Marc Kleine-Budde <mkl@pengutronix.de>
