+    CALLER          user from its host
+
+
+    DESCRIPTION:
+                    Add/delete  service
+					The function manipulates the command that register the service and call
+					to the NWP in order to add/delete the service to/from the mDNS package and to/from the DB.
+
+					This register service is a service offered by the application.
+					This unregister service is a service offered by the application before.
+
+					The service name should be full service name according to RFC
+                    of the DNS-SD - means the value in name field in SRV answer.
+
+					Example for service name:
+                    1. PC1._ipp._tcp.local
+                    2. PC2_server._ftp._tcp.local
+
+                    If the option is_unique is set, mDNS probes the service name to make sure
+                    it is unique before starting to announce the service on the network.
+                    Instance is the instance portion of the service name.
+
+
+
+
+    PARAMETERS:
+
+                    The command is from constant parameters and variables parameters.
+
+					Constant parameters are:
+
+                    ServiceLen                          - The length of the service.
+                    TextLen                             - The length of the service should be smaller than 64.
+                    port                                - The port on this target host.
+                    TTL                                 - The TTL of the service
+                    Options                             - bitwise parameters:
+                                                            bit 0  - is unique (means if the service needs to be unique)
+                                                            bit 31  - for internal use if the service should be added or deleted (set means ADD).
+                                                            bit 1-30 for future.
+
+                   The variables parameters are:
+
+                    Service name(full service name)     - The service name.
+                                                          Example for service name:
+                                                          1. PC1._ipp._tcp.local
+                                                          2. PC2_server._ftp._tcp.local
+
+                    Text                                - The description of the service.
+                                                          should be as mentioned in the RFC
+                                                          (according to type of the service IPP,FTP...)
+
+					NOTE - pay attention
+
+						1. Temporary -  there is an allocation on stack of internal buffer.
+						Its size is NETAPP_MDNS_MAX_SERVICE_NAME_AND_TEXT_LENGTH.
+						It means that the sum of the text length and service name length cannot be bigger than
+						NETAPP_MDNS_MAX_SERVICE_NAME_AND_TEXT_LENGTH.
+						If it is - An error is returned.
+
+					    2. According to now from certain constraints the variables parameters are set in the
+					    attribute part (contain constant parameters)
+
+
+
+	  RETURNS:        Status - the immediate response of the command status.
+							   0 means success.
