Path Name: /hp-ux_patches/s700_800/11.X/PHNE_18635

Symptoms:
	PHNE_18635:
	1. System may panic if promiscuous mode on a linkagg is
	   disabled between a cable disconnect and reconnect.
	2. After a certain sequence of link aggregate operations,
	   ping may fail.
	3. Load balancing among link aggregates ports does not work
	   for drivers which have checksum offloading.
	4. Link with the highest priority may not be selected when
	   transmitting data in hot-standby mode.
	5. Promiscuous mode is not re-enabled on a linkagg port when
	   the cable is disconnected and reconnected.
	6. Binding protocols in the range 128-255 may fail.
	7. MC/SG may not work properly during failover if the switch
	   is reset.

Defect Description:
	PHNE_18635:
	1. Unbound promiscuous data was not being routed through APA
	   code. So unbound promiscuous data was being sent to a
	   non-existent queue.
	Resolution:
	   Routed unbound promiscuous data through APA and APA makes
	   sure that the data is dropped if queue is removed.
	2. If the MAC address of linkagg changed, the ARP packet was
	   either not sent, or sent only once which could be lost if
	   the switch is unstable.
	Resolution:
	   Whenever MAC address changes, resend ARP packets at
	   5 second intervals for one minute.
	3. For drivers with checksum offloading, an extra 8 bytes of
	   data is present at the beginning of packet.
	Resolution:
	   MAC/IP address is now obtained from the packet based on
	   the driver type.
	4. Coding error in the bubble sort routine.
	Resolution:
	   Coding error was fixed.
	5. The promiscuous state of the linkagg was reset instead of
	   the promiscuous state of the port.
	Resolution:
	   The promiscuous state of the port was reset to original
	   value on cable reconnect.
	6. Incorrect casting of unsigned char was causing internal
	   failure during unbind for protocols in the range 128-255,
	   resulting in failure to bind later on.
	Resolution:
	   Did the correct casting.
	7. APA was returning a error when adding control information
	   during link down state which was causing the upper layers
	   to fail.
	Resolution:
	   Do not return error when adding control information to
	   the linkagg in linkdown state.

		 the patch cannot be deinstalled.  Please be careful
		 when using this feature.

	For future reference, the contents of the PHNE_18635.text file is 
	available in the product readme:
