APAR Error Description / Circumvention

-------------------------------------------------
The IFF_UP flag is set in the flags returned by the getifaddrs()
API for an IPv4 interface that has failed due to a duplicate IP
address. NETSTAT shows the status of the interface as Failed.

CORRECTION FOR APAR 'MA47995' :
-------------------------------
The IFF_UP flag should not have been set for any interface in
Failed state. The IFF_UP flag will now be correct for interfaces
that have failed due to duplicate IP address detection.

CIRCUMVENTION FOR APAR 'MA47995' :
----------------------------------
None.
