Defect/Fix: This problem happens when "x25stop" is issued after "zmasterd kill".This results
in a race condition in which even after the zcom cleanup routines are called, streams layer
calls the 'N2Z callback' service routine to queue the data to upper layers. But since the cleanup
routines have freed most of the relevant data structures like 'lhvcp' 'N2Z' service routine
causes a panic while accessing these data structures. Code changes have been made, so that
'N2Z' service routine returns immediately if a 'zcom' shutdown is in progress or complete.

Defect/Fix: This problem happens when application hangs before Accept and then closes the
socket. Closing of socket issues disconnect on all pending listens on a VC. While in hang, if
lower layer cleans this VC as part of remote disconnect request, and uses it for any outbound
connection, this second disconnect request(issued by socket closing) leads in to panic. Code
changes have been made to discard the second disconnect request.

Symptoms: x25stat reports incorrect information concerning flow control negotiation
Defect/Fix: This problem is related to misinterpretation of the flag used for getting these
negotiated parameters. The flag, which was assumed by ACC to display the thruput
parameters, was actually used by the x25 stack to display the flowcontrol parameters. Hence
for an "x25stat" command that issued while flowcontrol is set, ACC takes this as thruputflag
and responds with values related to thruputflag. Code changes have been made to set correct
flag, so that "x25stat" displays the flowcontrol information correctly when turned on.
