Branch: 	RHEL4

Modified files:
	ccs/daemon     : cnx_mgr.c 

Log message:
	BZ 418961
	Fix issue with endian conversion that caused problems for mixed architecture
	nodes on same subnet. Need to correct swap byte ordering of comm_header_t
	structure before copying into buffer and when dereferencing.
