APAR Error Description / Circumvention

-----------------------------------------------
Varying off a line description that is configured to use a port
on a 2CEC, 2CF3, 58FA, or 58FB Ethernet adapter takes over 1
minute to complete. After the vary off completes there is a 3400
0001 IOP support LIC Log entry created. This problem is
intermittent.

CORRECTION FOR APAR MA47985 :
-----------------------------
There is a timing window that can occur when varying off a line
description where the device driver fails to free up some
internal storage. This results in the device driver failing to
complete vary off processing for the line description. After
approximately 1 minute, the vary off processing times out and
completes successfully, even though the device driver did not
complete its processing. It may be necessary to re-IPL the IOP
associated with the line description before the line description
can be varied on again.

This problem can only occur for 2CEC, 2CF3, 58FA, and 58FB
Ethernet adapters.

This fix eliminates the timing window so the device driver
successfully completes vary off processing.

CIRCUMVENTION FOR APAR MA47985 :

None.
