 ERROR DESCRIPTION:
 VM TCP/IP is no longer able to communicate after Microcode
 upgrade to OSA express adapter. Problem only occurs on VM TCP/IP
 R3A0 and R410. New releases of VM TCP/IP already have a change
 that resolves the problem.
 No error condition is apparent. The device appears to be
 READY but no data transfer takes place.

 PROBLEM SUMMARY:
 ****************************************************************
 * USERS AFFECTED: All users of z/VM TCP/IP Level 3A0 and 410   *
 *                 using OSD devices.                           *

 * RECOMMENDATION: APPLY PTF                                    *
 ****************************************************************
 After upgrading the OSA device with a Microcode update, no
 connectivity is possible with OSD devices.  The device status
 is Ready and there are no error messages.
 The Microcode update on the OSD device needs to be communicated
 to z/VM TCP/IP stack to ensure this condition is handled
 properly.
 
 PROBLEM CONCLUSION:
 The QDIO buffer handler (TCQDIO) has been updated to set the
 appropriate flag (QDIO_HEADER_FLAG_UNICAST) in the QDIO
 QDIO header.  Macro TCQDIOCO was updated to define the
 constants.
