 Routing messages
 CONFIG_RTNETLINK
-  If you say Y here and create a character special file /dev/route
-  with major number 36 and minor number 0 using mknod ("man mknod"),
-  you (or some user space utility) can read some network related
-  routing information from that file. Everything you write to that
-  file will be discarded.
+  If you say Y here, userspace programs can receive some network
+  related routing information over the netlink. 'rtmon', supplied
+  with the iproute2 package (ftp://ftp.inr.ac.ru), can read and
+  interpret this data.  Information sent to the kernel over this link

 Netlink device emulation
 CONFIG_NETLINK_DEV
+  This option will be removed soon. Any programs that want to use

   This is a backward compatibility option, choose Y for now.
