APAR Error Description / Circumvention

-----------------------------------------------
Ending a TCP/IP *IP4DHCP interface times out and does not fully
reset the interface.

CORRECTION FOR APAR MA42620 :
-----------------------------
A separate task used to manage the DHCP protocol failed to check
that an operation had been canceled if it kept receiving DHCP
messages intended for another DHCP client. (The messages were
broadcast so they are received by all DHCP clients on the same
subnet.) This prevented the end of the DHCP interface from
completing.

The DHCP protocol task has been corrected to better detect that
an operation had been canceled.

CIRCUMVENTION FOR APAR MA42620 :
--------------------------------
None.
