      1 ## IPv6 Autoconfiguration
      2 ## ======================
      3 ##
      4 ## Enable IPv6 neighbour discovery for an interface and allow it
      5 ## to participate in router solicitation/router advertisement.
      6 ##
      7 ## You need this if you want to get an IPv6 address (or addresses)
      8 ## whether by stateless allocation (SLAAC) or by DHCP6. You don't
      9 ## need this on interfaces that are members of bridges, because they
     10 ## shouldn't have addresses of their own.
