 ****************************************************************
 * USERS AFFECTED: All users of z/VM TCP/IP FL420 planning to   *
 *                 use HiperSockets                             *
 ****************************************************************
 * PROBLEM DESCRIPTION: With z/VM 4.2.0 APAR VM62938, z/VM      *
 *                      TCP/IP users will no longer be able     *
 *                      to use Guest LAN HiperSockets devices   *

 This APAR is required to support the latest GA
 level of the HiperSockets hardware.
 
 PROBLEM CONCLUSION:
 
 TEMPORARY FIX:
 
 COMMENTS:
 This APAR brings z/VM's TCP/IP support of HiperSockets
  to the z/900 GA 2 level.  The output of the NETSTAT DEVLINKS
 command will also display the Maximum Frame Size (MFS) permitted
 for the given HiperSockets link.  This enhancement requires an
 enhancement to the base operating system provided by VM APAR
 VM62938 (to CP).
