Oliver Hartkopp f8e0edeaa0 can: j1939: j1939_send_one(): fix missing CAN header initialization ... commit 3eb3d283e8 upstream. The read access to struct canxl_frame::len inside of a j1939 created skbuff revealed a missing initialization of reserved and later filled elements in struct can_frame. This patch initializes the 8 byte CAN header with zero.
