  16356 - Trigger the FFST probe ISTAUC01 because the EE Port FSM
  processor (ISTAUCPF) is receiving an RPH for DACTLINK processing
  and this cannot be handled.
  16263 - Inop dump does not take the dump of VTAM and TCP/IP
  address spaces dump when RNICID is specified.
  16627 - The stack is not enforcing the architectural limit of
  255 RKEYs in a link group. If we exceed this limit, we cannot
  exchange all RKEYs with the peer.
  16884 - Abend0C4 occurs in module ISTSRIDQ
  

Problem conclusion

• 16356 - Change ISTAUCPF to handle DACTLINK RPHs for EE
  Verification failures. Code was modified with code related to
  APAR OA42734 to handle DACTLINK processing in the port FSM
  processor.
  16263 - inopdump macro has been changed to dump both VTAM and
  TCP/IP address spaces when  RNICID is specified.  The following
  module have been recompiled to use the updated code of inopdump
  macro:
     ISTSRIDQ, ISTSRIWC, ISTSRIWD, ISTSRIWI, ISTSRRIE, ISTSRRRV,
  ISTSRICL and ISTSRIS8.
  16627 - Change EZBSRUTL to ensure that a link group does not
  exceed 255 local RKEYs. The stack will fall back to IP for any
  connection which would require exceeding this limit.
  
  
  Also changed ISTSRIS8 to correctly set a field in the server
  side DM_ACT_CNF signal (noticed from a stack ctrace).
  16884 - While polling a read completion queue (CQ) for inbound
  data, an Abend0C4 occurs in ISTSRIDQ trying to queue a
  CM_Deact_Req Tipac to the SRNCB.  The error was expected as
  PFIDs were being taken offline, but the abend trying to shutdown
  the device is not expected.  Abend occurs because the RPH is not
  set in Reg1 when the TPQUE macro is issued.
  Note: A logical route of the fix for APAR OA42734 has been
  included in this APAR.
