APAR Error Description / Circumvention

-----------------------------------------------
An ACK was not sent for incoming data when there is outgoing
data that has not been ACKed at the time of the incoming data
packet.

CORRECTION FOR APAR MA41966 :
-----------------------------
The code was updated to ACK incoming data appropriately.

CIRCUMVENTION FOR APAR MA41966 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR MA41795 :
-----------------------------------------------
ioctl(SIOCSENDQ) is returning 0 for the number of bytes unACK'ed
instead of returning an error when the connection is closed
before sent data is ACK'ed.

CORRECTION FOR APAR MA41795 :
-----------------------------
An error will be returned on ioctl if the connection is closed
before all sent data has been ACK'ed.

CIRCUMVENTION FOR APAR MA41795 :
--------------------------------
None.
