Note: This Service Pack addresses the following HIPER issue:

HIPER/Pervasive:  On systems with PowerVM firmware , the following problems related to SR-IOV were fixed:
1) A problem was fixed for new or replacement SR-IOV adapters with feature codes EN15 and EN17 being rendered non-functional when moved to SR-IOV mode. This includes cards moved from dedicated device mode, newly installed adapters, and FRU replacements. This problem occurs when the adapter firmware is updated to the 10.2.252.x levels from 11.x adapter firmware levels.
2) A problem was fixed for certain SR-IOV adapters where SRC B400FF01 errors are seen during vNIC failovers and Live Partition Mobility (LPM) migration of vNIC clients.This may also result in errors seen in partitions (for example, some partitions may show LNC2ENT_TX_ERR).
3) A problem was fixed where network multicast traffic is not received by a SR-IOV logical port (VF) network interface for a Linux partition. The failure can occur when the partition transitions the network interface out of promiscuous or multicast promiscuous mode.
These fixes update adapter firmware to 10.2.252.1939  for the following Feature Codes:   EN15, EN17, EN0H, EN0J, EN0M, EN0N, EN0K, EN0L, EL38, EL3C, EL56, and EL57.
The SR-IOV adapter firmware level update for the shared-mode adapters happens under user control to prevent unexpected temporary outages on the adapters.  A system reboot will update all SR-IOV shared-mode adapters with the new firmware level.  In addition, when an adapter is first set to SR-IOV shared mode, the adapter firmware is updated to the latest level available with the system firmware (and it is also updated automatically during maintenance operations, such as when the adapter is stopped or replaced).  And lastly, selective manual updates of the SR-IOV adapters can be performed using the Hardware Management Console (HMC).  To selectively update the adapter firmware, follow the steps given at the IBM Knowledge Center for using HMC to make the updates:   https://www.ibm.com/support/knowledgecenter/HW4M4/p8efd/p8efd_updating_sriov_firmware.htm.
Note: Adapters that are capable of running in SR-IOV mode, but are currently running in dedicated mode and assigned to a partition, can be updated concurrently either by the OS that owns the adapter or the managing HMC (if OS is AIX or VIOS and RMC is running).
