              The *NETWORK control block is divided into two
              sections.  A fixed header portion which contains a
              sender and a reply section.  The sender area
              contains common information related to the task
              sending the request.  Whereas the reply area
              contains common information related to a task
              replying to a SEND_REQUEST with a synchronous reply
              it received from another system using HCPSOCK
              SEND_REPLY.
              The second section is a operation code specific area
              which is mapped differently per *NETWORK operation
              code.  This area can be mapped differently depending
              on whether it is a HCPSOCK SEND_REQUEST or
              SEND_REPLY.  Reference the DSECT for a specific
              operation code for the appropriate data mappings.

      Function   :
         To insure each system member of a SSI can generate
         a unique MAC Address, the customer must setup the
         appropriate MAC Service's VMLAN definitions.  This
         *NETWORK request will verify this system's MACPREFIX
         and USERPREFIX settings follow the rules before
         allowing it to become an active member of the SSI.
         The Verify MAC Prefix request will send this system's
         current MACPREFIX and USERPREFIX to all SSI
         members.  The SSI members receiving this request
         will verify that the MACPREFIX in the request doesn't
         match their MACPREFIX and the USERPREFIX does match
         their setting.  If both MAC prefix values are
         acceptable, then an affirmative reply will be returned
         to this system.  Otherwise a negative reply is
         returned.

      NE1BK Operation Code x'0001' MAC Address Request
      Function   : *NETWORK Request which will perform one of the
                following functions:
      1) Verify MAC Address Request
            A "Verify MAC Address Request" multicast is sent to
            all other JOINED members of a SSI prior to
            assigning a MAC Address for a network device.  The
            receiving SSI member{s} will check to see if the
            specified MAC Address in the SEND_REQUEST is in use
            on their system.  If the MAC Address is not found,
            an affirmative respones via a SEND_REPLY is returned
            in the response area of common *NETWORK header
            indicating the address is not in use.  An unanimous
            affirmative response from all the active members
            will allow the issuing system to network device to
            be defined, attached to a guest or the Diagnose x26C
            Subcode 30 MAC Service to complete successfully.
            Conversely a negative response from any system will
            prevent the network device from being added to the
            guest's virtual configuration.
              Optional Prefix Check  (NE1FLAGS.NE1PFXCK = ON)
              ***************------
              If NE1FLAGS.NE1PFXCK is ON, then an additional MAC
              PREFIX check will be performed by each SSI member.
              In addition to testing whether the specified 6
              byte MAC Address is allocated, it will also verify
              that the MAC PREFIX (first 3 bytes of the MAC
              Address) doesn't match its currently set SYSTEM,
              USER or ENSEMBLE PREFIX settings.  If the MAC
              PREFIX is the same as an SSI Member, that member
              will return a negative response.  This test is
              necessary in order to verify a 6 byte explicit
              user MAC Address assignment by a customer or guest
              will never conflict with a system MAC assigned by
              any SSI member.
       2) Release MAC Request
            A "Release MAC Request" multicast will be sent from
            an active SSI member to all other active members
            when it is done using a foreign assigned MAC on his
            system.  This will allow the system image which
            created (owns) the MAC Address to mark it as
            available for reuse in his Assigned MAC MLT.
            When a system receives a "Release Foreign MAC
            Request", it will verify the user which owns the MAC
            Address is not locally owned prior to removing the
            MAC from his Assigned MAC MLT.  This prevents the
            MAC Address from being removed when a release
            request occurs in the middle of a live guest
            migration.  If the migration fails fails, the guest
            will not be relocated and it will remain running.
            Notes      : The receiving system will NOT REPLY to this
                  request with a SEND_REPLY.
       3) Confirm MAC Address Allocation
            A "Confirm MAC Address Allocation" multicast is sent
            out by this system to all other active SSI members
            within the cluster to confirm the allocation of a
            MAC Address by his system.  This allows the other
            SSI members to keep track of user defined or MAC
            Address which they own that are currently in use by
            network devices on this system.  This request is
            broadcast whenever a user defined or a foreign MAC
            Address is allocated on this system image.
            Notes      : The receiving systems will NOT REPLY to this
                  request with a SEND_REPLY.

                An "Assigned MAC Table Synchronization" request
                is sent to each active member of the SSI when
                a system joins a SSI.  At SSI JOIN time,
                both the candidate and target systems will
                synchronize MAC Addresses matching the candidate
                and target system and user's MACPREFIXs.  This

                The SEND_REQUEST sends the data below to the

      Function   :
         The 'Verify Ensemble Data' request is sent to all
         other JOINED members of an SSI.  If the receiving
         SSI member is currently in the ensemble, it will check
         to see if the specified Ensemble Function Level matches
         it's own.  If it does, it will make sure that the
         Ensemble ID matches.  If the Ensemble Function Level
         and the Ensemble ID match what is in use or the
         receiving SSI member is not currently in an ensemble,
         an affirmative response is returned via the Send_Reply
         response area of the common *Network header indicating
         that the requesting SSI member may join the ensemble.
         If either the Ensemble ID or the Ensemble Function
         Level do not match what is in use, a negative response
         is returned via a Send_Reply along with the currently
         active Ensemble Function Level or Ensemble ID.
         A unanimous affirmative response from all active
         members will allow the requesting member to join the
         ensemble.
