* tests/can_overrun1.c (can0_thread): Fix the length of the data in the message. Add a delay to allow the CAN device to process the packets. * test/can_txcevent.c: (can0_thread): Add a delay to allow the CAN device to process the packet.s * src/loop_can.c (FIFO_SIZE): Changed to one more than the TX queue size. If it is less, the loopback tests don't pass because packets don't get transmitted.
