 * 1                    DESCRIPTION
 ****************************************************************************
 * Instruct compiler to assume 16-bit alignment for the struct enclosed in
 * two ipcom_align16.h includes, and also to avoid padding. Example:
 *
 *      #include "ipcom_align16.h"
 *      typedef IP_PACKED1 struct mystruct
 *      {
 *          ...
 *      }
 *      IP_PACKED2 mystruct;
 *      #include "ipcom_align16.h"
 */
