Path Name: /hp-ux_patches/s700/10.X/PHNE_19541

Symptoms:
	PHNE_19541:
	1. System with PCI FDDI interface hangs.

	PHNE_18735:
	1. The unbound promiscuous stream does not intercept
	   outbound packets when in promiscuous mode.
	2. "No entry for fddipciadmin" will be returned from the
	   command: man fddipciadmin
	3. System may hang when there is high inbound traffic over
	   PCI FDDI interface.
	4. System may panic with panic string "Spinlock timeout
	   failure:" when there is high outbound traffic over
	   PCI FDDI interface.

	PHNE_16361:
	1. Data transfers over an NFS mount can hang and time out.

Defect Description:
	PHNE_19541:
	1. System hangs due to negative spinlock depth.

	PHNE_18735:
	1. Driver does not loopback outbound packets when in
	   promiscuous mode.
	Resolution:
	   If the global flag, lanc_outbound_promisc_flag, is set,
	   the driver will loopback outbound packets to an unbound
	   promiscuous stream.
	2. The man page for fddipciadmin was not in versions
	   B.10.20.01 or B.10.20.03 of the driver.
	Resolution:
	   The man page has been added to this patch.
	3. Under heavy inbound traffic, the IP receive queue may
	   get full and attempts by the driver to queue the
	   messages onto the queue could fail. These messages were
	   not getting freed, resulting in a system memory leak.
	Resolution:
	   The driver has been changed to detect such conditions
	   and free the message buffers.
	4. Under heavy outbound traffic, the driver may hold a
	   spinlock for a significant amount of time, while it
	   processes all pending transmit completions.
	Resolution:
	   The driver has been changed to process fewer transmit
	   completions on receiving a transmit completion interrupt,
	   thereby cutting down on time the spinlock is held.

	PHNE_16361:
	1. The data which is sent to the driver from UDP can be in
	   a format which requires additional transmit headers to
	   be prepended.  The headers were not properly prepended
	   to the data.

	------------------------------------------------------------
	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_19541

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_19541.depot

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHNE_19541.  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_19541.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_19541.depot of=/dev/rmt/0m bs=2k
