SYNOPSIS

                  uint32_t options;
                  uint32_t comp_mask;
              };

       vendor_id
              Unique  identifier  of  the provider vendor on the network.  The providers will set

              users.

       comp_mask
              Bitmask specifying what fields in the structure are valid.
