Currently, manually adding an IPv6 prefix to ifconfig is a bit of a pain, as
one has to manually create the host id portion.

eg
  Mac address ab:ad:12:34:56:78
    ->
  ifconfig ex0 inet6 fec0::1:abad:12ff:fe34:5678

To make things easier, I'm thinking of patching ifconfig to allow just a /64
prefix to be given with the host id added automatically by ifconfig.

Is this a bad idea?

If not, is there a preferred syntax?

eg
  ifconfig ex0 inet6 fec0::1:auto/64

Thanks
