WD8003/WD8013 Driver Update

1. General Description

	This patch contains an updated driver for the WD8003/WD8013 network
	adapter cards.  The updated driver corrects an error in the 
        handling of "loopback" messages that sometimes caused garbled 
        messages to be sent to loopback destinations (note: only the 
        loopback copy of the message was affected) and also an error 
        that precluded concurrent use of the driver by both the IPX and 
        an OSI stack because messages intended for one would be 
        erroneously directed to the other.


2. New Features

	None


3. Software Notes and Recommendations

	This patch should be installed on all UnixWare 1.1.1, 1.1.2 
        or 1.1.3 systems which have the WD8003/WD8013 (wd) driver installed.

	This patch requires UnixWare Update 1.1.1, 1.1.2 or 1.1.3 
        and the wd driver to be installed on the system.  The package 
        will NOT install if the required system configuration is not present.


4. Hardware Notes and Recommendations

	None 


5. Installation Instructions

	Depending on the format:

        If this PTF was delivered on a diskette, then (as "root")

		pkgadd -d diskette1

	should install this patch.

	Otherwise, if you have a file such as "ptf171" which is in a "stream"
	format, then (as "root")
		pkgadd -d <pwd>/ptf171 
	will work.
	
	After installing this patch, a system reboot will be needed to rebuild
	the kernel and incorporate the updated driver(s).
