Just for playing I disabled auto link-local address generation, then I 
found that "ifconfig fxp0 inet6 fec0::1 delete" worked after I added that 
one (without alias, which was my testing reason). Then I also deleted the 
eui64 address and wanted to reassign it.
Another reason I tried to use the -eui64 option with ifconfig was because 
my fwe0 got no inet6 address!
Either the man page of ifconfig is wrong or something else, I couldn't get 
a working syntax with option eui64.
