PROBLEM:        (QAR 49764)     (Patch ID: OSF415-400171)
********
When attempting to establish a number of XTI connections, > 500, the client
system hangs and becomes inoperable.  This fix will allow an application to
issue a large number of connect requests (up to 3K connections).

This patch fixes the problem of t_optmgmt() T_NEGOTIATE calls returning
T_SUCCESS, but not actually negotiating the options.

This patch fixes a kernel memory fault panic in the xti_discon_req() routine.
A representitive stack trace is:

Under some conditions, an xti application which attempts to disconnect an
endpoint will precipitate a kernel memory fault panic from the xti_discon_req
routine.

********
Multithreaded TLI application blocks forever.  dbx session will show that
it blocks in the t_look() library routine.

For this to happen, it is necessary that t_look() is called twice. Because it
is called internally by a number of other TLI library routines, application
can hang under all sorts of scenarios.

This patch fixes a problem with the implementation of the TPI interface.
This problem occurs if you are using Digital's XTI libxti library with a
third-party (non-Digital) STREAMS driver.

PROBLEM:  (BRO101146) (Patch ID: OSF415-405237)
********
This patch fixes a problem that occurs on a system when running STREAMS. 
The system panics with the following error message:

  "kernel memory fault"

A sample stack trace is shown as follows:
