  performance enhancement that might be beneficial for OSA
  interfaces with a high volume of inbound network bulk or
  streaming traffic.

  For z/OS Communications Server V2R4 and V2R5, this APAR has a
  dependency on SNA APAR OA62831 which requires both APARs to be
  applied concurrently; unexpected results may occur if both APARs
  are not applied concurrently.
  
  
  The MCL level needed for z16 is MCL Alias P30739.004.  This
  function is not supported in hardware levels prior to z16.
