+	* 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.

 	* doc/synth_test.ecm: Import file for running the tests on synth.
