ENGINEERING RELEASE NOTES
-------------------------

Title
-----

PTF2190 - ODI Core Drivers Patch

Product And Version
-------------------

UnixWare 2.01, UnixWare 2.02, UnixWare 2.03

Abstract
--------

Enables the LLC2 and RAW interface modes for ODI Network
Interface Card drivers.  Suppresses Token Ring Source Routing
information for nodes attached to the local ring.  Supersedes
PTF2087.

Symptom
--------

- Various errors are observed by applications attempting to use
  the LLC2 or RAW interface modes with the ODI Network Interface
  Card drivers.

- Even though Source Routing is not required for stations on the
  same ring, a station on the same ring that is not using Source
  Routing cannot communicate with the UnixWare station.


SOLUTION SPECIFICS
------------------

General Description.
-------------------

This patch installs a updated set of ODI core drivers (which
implement the ODI framework to support ODI-compliant Network
Interface Card drivers).  The updated drivers correct several
problems that have been observed when the LLC2 or RAW mode is
used.  The Token Ring Source Routing information field is now
suppressed for nodes attached to the same ring.

This PTF supersedes PTF2087 and includes all changes contained in
it, as well as additional changes.


New Features.
------------

None
