APAR Error Description / Circumvention

-----------------------------------------------
Under heavy load, an Ethernet port with type 576E may stop
sending and receiving traffic.  An Product Activity Log entry
with SRC B025A6D9 will be created.  The error is only recovered
by IPLing the associated virtual IOP, either by using Hardware
Service Manager or doing VRYCFG with RESET on the associated
line description.

CORRECTION FOR APAR MA37845 :
-----------------------------
Direct Memory Access timeout completions were not being disabled
under some circumstances, allowing this error to occur.
Licensed Internal Code has been changed to ensure that DMA
timeout completions are uniformly disabled.

CIRCUMVENTION FOR APAR MA37845 :
--------------------------------
None.
