Problem Description: 

1145294	Problem is seen on active networks where the network interface on
	Classic's, LX's, Sparcstations 5 and 20 (based on MACIO) may hang
	and ignore incoming ethernet packets after receipt of a giant packet
	that is greater than 4096 bytes. This fix will detect this condition
	and reset the ethernet interface to prevent the interface from hanging.

1170392	Under heavy loads (as a result of heavy network activity or disk
	activity), SS10 hard hangs with le0:memory errors.
