Problem Description: 

1184046 On an SS10/SS20 with FSBE , if etherfind or snoop is
        started on le1, the le1 interface hangs and needs to be reset by
        an ifconfig or a reboot.

1177296 The ethernet interface hangs when transferring a large file (rdump ,
        ftp, rcp or cp from NFS) but only when using AUI. When using TP,
        it works fine .The problem  happens on SS5 or MACIO based systems.

1163300	le0 ethernet interface suddenly freezes during rdump

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