I just now discovered that the hme network interface seems to
return duplicates of all outgoing packets when in promiscious
mode.  If I run tcpdump locally on the Ultra 5, and ping the
system from another host, tcpdump prints two copies of each 'echo
reply' packet.  Could this behavior explain why the IPv6 stack
thinks that the hme interface has a duplicated IPv6 address?
