-// DragonFly BSD, FreeBSD 7 through 11, NetBSD 6 and above, and
-// OpenBSD 5.6 and above.

-// A RouteMessage represents a message conveying an address prefix, a
-// nexthop address and an output interface.
-//
-// Unlike other messages, this message can be used to query adjacency
-// information for the given address prefix, to add a new route, and
-// to delete or modify the existing route from the routing information
-// base inside the kernel by writing and reading route messages on a
-// routing socket.
-//
-// For the manipulation of routing information, the route message must
-// contain appropriate fields that include:
-//
-// Version = <must be specified>
-// Type = <must be specified>
-// Flags = <must be specified>
-// Index = <must be specified if necessary>
-// ID = <must be specified>
-// Seq = <must be specified>
-// Addrs = <must be specified>
-//
-// The Type field specifies a type of manipulation, the Flags field
-// specifies a class of target information and the Addrs field
-// specifies target information like the following:
-//
-// route.RouteMessage{
-// Version: RTM_VERSION,
-// Type: RTM_GET,
-// Flags: RTF_UP | RTF_HOST,
-// ID: uintptr(os.Getpid()),
-// Seq: 1,
-// Addrs: []route.Addrs{
-// RTAX_DST: &route.Inet4Addr{ ... },
-// RTAX_IFP: &route.LinkAddr{ ... },
-// RTAX_BRD: &route.Inet4Addr{ ... },
-// },
-// }
-//
-// The values for the above fields depend on the implementation of
-// each operating system.
-//
-// The Err field on a response message contains an error value on the
-// requested operation. If non-nil, the requested operation is failed.
