		Changing link address with 100bt makes ARP fail.

Path Name: /hp-ux_patches/s700_800/10.X/PHNE_15781

Symptoms:
	PHNE_15781:
	The following symptoms are seen for PHNE_15781:
	1. Some sequences of packets will cause poor receive
	performance.

	PHNE_15636:
	The following symptoms are seen for PHNE_15636:
	1. After being configured down, the driver continues to
	pass received packets to the IP layer.

	PHNE_15151:
	The following symptoms are seen for PHNE_15151:
	1. After a cable disconnection, the operation status in
	the lan MIB was not correctly updated.
	2. System panic in the btlan4 driver code.
	3. The driver will receive packets without regard to the
	encapsulation type(s) configured on the interface.  This
	can cause the link to be unable to transmit if ARP packets
	update the ARP cache with incorrect encapsulations.

	PHNE_14974:
	The following symptoms are seen for PHNE_14974:
	1. The driver is unable to receive IP Multicast frames.
	2. After a cable disconnect or a lanadmin reset, IP
	Multicast frames are no longer received.

	PHNE_13940:
	The following symptoms are seen for PHNE_13940:
	1. When the AUI port is connected lanscan still shows
	the hardware state as being down.
	2. Driver reports receive errors under heavy traffic
	3. Manual Speed and Duplex configuration is now enabled.

	PHNE_12400:
	The following symptoms are seen for PHNE_12400:
	1. System panic in the btlan4 driver code.
	2. HSC 100BT port hung.

	PHNE_11229:
	The following symptoms are seen for PHNE_11229.
	1. Changing the link address with 100bt makes ARP fail.
	2. GSC 100BT driver reports incorrect statistics.
	3. Lanadmin shows incorrect (bogus) value for outbound
	queue on HSC 100BT.
	4. Receive performance will not be as good as with this
	patch.
	5. FTP hangs.
	6. Problem with 10BT and noheartbeats.
	7. Low performance due to IEEE SNAP packets not being
	logged and going through expensive lanc_logging.
	8. Cable disconnect/reconnect interrupts are not always
	acknowledged.
	9. DHCP does not work correctly with GSC 100BT.

Defect Description:
	PHNE_15781:
	The following defect descriptions are for PHNE_15781:
	1. When the card receives a packet, it will only trigger
	an interrupt if there is not already a receive interrupt
	outstanding.  There was a small timing window in the driver
	where the driver had finished processing the received
	packets, but had not informed the card to generate a new
	interrupt.  This caused the last packet to be delayed.

	PHNE_15636:
	The following defect descriptions are for PHNE_15636:
	1. The driver's fast path receive code did not check the
	correct flags before passing the packet up the network
	stack.

	PHNE_15151:
	The following defect descriptions are for PHNE_15151:
	1. The 100BaseT driver was updating the interface state
	before it was informing the MIB code that the cable had
	been disconnected.  Since the interface state was already
	marked down, the MIB code believed no state change had
	occurred and did not update the operation status.
	2. The 100BaseT driver was releasing the buffers
	after the upper network layer had completed processing.  If
	the upper network layer encountered a pullup error, it would
	free the buffer itself.  The btlan4 driver would then free
	the buffer again causing a panic.
	3. The 100BaseT driver passed received packets to the upper
	layer without first checking if the encapsulation was
	configured on the interface.

	PHNE_14974:
	The following defect descriptions are for PHNE_14974:
	1. After the IP layer joined an IP multicast group, the
	driver did not correctly update the fast ethernet card's
	address list.  Without the correct address list on the
	card, IP multicast frames were not received.
	2. After a lanadmin reset or a cable disconnect, the card's
	address list is reset.  The driver failed to update the
	card with the correct address list.  This prevented IP
	multicast frames from being received.

	PHNE_13940:
	The following defect descriptions are for PHNE_13940:
	1. The AUI port was not being properly initialized.
	2. Modified receive path to ensure efficient processing
	under heavy inbound traffic

	PHNE_12400:
	The following defect descriptions are for PHNE_12400:
	1. Under heavy inbound traffic for a long period of time,
	btlan4 driver will eventually exhaust all the receive
	descriptors and it can cause port hang or system panic.

	PHNE_11229:
	The following defect descriptions are for PHNE_11229.
	1. Changing link address with 100bt makes ARP fail.
	2. GSC 100BT driver reports incorrect statistics.
	3. Lanadmin shows incorrect (bogus) value for outbound
	queue on HSC 100BT.
	4. Modified receive path to increase performance.  Use
	schednetisrmq instead of the older schednetisrsq.
	5. Transmit and Receive data structures were not properly
	zero'ed out during initialization.  This caused FTP's to
	occasionally hang the system.
	6. Noheartbeat errors must be disabled when in 10BT mode.
	Otherwise, output packet counts will not be properly
	updated.
	7. Low performance due to IEEE SNAP packets not being
	logged and going through expensive lanc_logging.
	8. Transmit and Receive interrupts are not acknowledged
	during cable disconnect/reconnect conditions.
	9. Fixed bug in BTLAN3_DO_FAST_IN which failed to check the
	strip header flag.  This caused the GSC 100BT driver to not
	work correctly with DHCP.

	before installing this patch.
	------------------------------------------------------------
	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_15781

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_15781.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_15781.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_15781.  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_15781.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_15781.depot of=/dev/rmt/0m bs=2k
