    kernel - Deal with inconsistencies between IP aliases and primary IPs
    These changes allow normal IP aliases with proper network masks to be
    ifconfig'd instead of forcing people to use non-obvious /32's for their
    IP aliases.  It may also be possible to use overlapping subnets with
    this change but this is not tested.
    * When ifconfig'ing an interface with aliases using the correct netmask
      instead of a /32, the network route will point to only one of the
      Trying to connect to a local IP alias wound up failing due to the
      mismatch between the network route's interface address (ifaddr)
      entry and the actual ifaddr being requested.  The target was not
      being considered a local address when it was.
    * Fix in_addroute()'s detection of local host routes when cloning a
      route to check against all aliases instead of the one the gateway
      network route happens to be pointed to, and adjust the route entry
      This fix also properly sets RTF_LOCAL for all such cloned routes
      whereas before RTF_LOCAL was only being set for the interface's
      primary IP.
    * Minor syntax adjustments and documentation changes.
