Patch Name: PHNE_14270

Patch Description: s700 10.20 CORE PCI 100Base-T cumulative patch

Creation Date: 98/02/23

Post Date:  98/03/26

Hardware Platforms - OS Releases:
	s700: 10.20

Products: N/A

Filesets:
	Networking2.CORE100-KRN

Automatic Reboot?: Yes

Status: General Superseded

Critical: No

Path Name: /hp-ux_patches/s700/10.X/PHNE_14270

Symptoms:
	PHNE_14270:
	CORE 100BT hangs when very long packets are received on the
	interface.

	Without the promiscuous multicast enabled on the card, IP
	Multicast traffic to the individual IP multicast addresses
	is not received. Also, the internal loopback of the
	multicast packets where the packet length is less than 60
	bytes, and data in the packet is distributed over multiple
	buffers.

	PHNE_13675:
	CORE 100BT can hang on MP workstations under high stress.

	PHNE_12953:
	Applications attempting to set IP multicast address on the
	Core PCI 100Base-T network interface will receive error.
	Applications attempting to enable promiscuous traffic mode
	on the Core PCI 100Base-T network interface will receive
	error.

Defect Description:
	PHNE_14270:
	When a very long packet is received on the CORE 100BT
	interface, it causes the receive watchdog timer to timeout,
	resulting in shutdown of the receiver and transmitter, and
	raising corresponding interrupt to the driver. The driver
	simply puts out the warning message on the console, but
	fails to restart the receiver and transmitter.

	The driver fails to add the individual IP multicast
	addresses (filters) correctly on the card. Also, for the
	loopback problem, the driver does not correctly pad to
	60 bytes for packets smaller than 60 bytes long.

	PHNE_13675:
	Under certain conditions some subtle errors the receive path
	of the driver can be exposed causing link failure such as
	hung link etc.

	PHNE_12953:
	CORE PCI 100Base-T does not support IP Multicasting and the
	promiscuous - physical, multicast, SAP - traffic.

Installation Instructions:

	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHNE_14270

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_14270.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHNE_14270.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHNE_14270.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHNE_14270.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHNE_14270.depot of=/dev/rmt/0m bs=2k
