APAR Error Description / Circumvention

-----------------------------------------------
When outbound packets temporarily overrun the adapter, those
packets are queued and send is later reattempted during a
subsequent transmit over the adapter. In some cases, these
packets could be delayed until TCP retransmits much later.

CORRECTION FOR APAR MA44301 :
-----------------------------
A timer will be started to ensure the delay in reattempting to
send the packets is not more than 50ms. In most cases the
packets would have been reattempted well before that point, but
this sets an upper bound on the delay.

CIRCUMVENTION FOR APAR MA44301 :
--------------------------------
None.
