New Revision: 197139
URL: http://svn.freebsd.org/changeset/base/197139

Log:
  Integrate rc.d/network_ipv6 into rc.d/netif:
  
  - Add rc.d/stf and rc.d/faith for stf(4) and faith(4).
  - Remove rc.d/auto_linklocal and rc.d/network_ipv6.
  - Move rc.d/sysctl to just before FILESYSTEMS because rc.d/netif
    depends on some sysctl variables.
