 * sc_type values
 * These represent commands that the SAC sends to a port monitor.  These
 * commands are divided into "classes" for extensibility.  Each subsequent
 * "class" is a superset of the previous "classes" plus the new commands
 * defined within that "class".  The header for all commands is identical;
 * however, a command may be defined such that an optional data portion may
 * be sent in addition to the header.  The format of this optional data piece
 * is self-defining based on the command.  Important note:  the first message
 * sent by the SAC will always be a class 1 message.  The port monitor
 * response will indicate the maximum class that it is able to understand.
 * Another note is that port monitors should only respond to a message with
 * an equivalent class response (i.e. a class 1 command causes a class 1
 * response).
