-.SH NAME
-rtnetlink \- Linux routing socket
-.SH SYNOPSIS
-.nf
-.B #include <asm/types.h>
-.B #include <linux/netlink.h>
-.B #include <linux/rtnetlink.h>
-.B #include <sys/socket.h>
-.P
-.BI "rtnetlink_socket = socket(AF_NETLINK, int " socket_type ", NETLINK_ROUTE);"
-.fi
-.SH DESCRIPTION
-Rtnetlink allows the kernel's routing tables to be read and altered.
-It is used within the kernel to communicate between
-various subsystems, though this usage is not documented here, and for
-communication with user-space programs.
-Network routes, IP addresses, link parameters, neighbor setups, queueing
-disciplines, traffic classes and packet classifiers may all be controlled
-through
-.B NETLINK_ROUTE
-sockets.
-It is based on netlink messages; see
-.BR netlink (7)
-for more information.
-.\" FIXME . ? all these macros could be moved to rtnetlink(3)
-.SS Routing attributes
-Some rtnetlink messages have optional attributes after the initial header:
-.P
-.in +4n
-.EX
-struct rtattr {
-    unsigned short rta_len;    /* Length of option */
-    unsigned short rta_type;   /* Type of option */
-    /* Data follows */
-};
-.EE
-.in
-.P
-These attributes should be manipulated using only the RTA_* macros
-or libnetlink, see
-.BR rtnetlink (3).
-.SS Messages
-Rtnetlink consists of these message types
-(in addition to standard netlink messages):
-.TP
-.B RTM_NEWLINK
-.TQ
-.B RTM_DELLINK
-.TQ
-.B RTM_GETLINK
-Create, remove, or get information about a specific network interface.
-These messages contain an
-.I ifinfomsg
-structure followed by a series of
-.I rtattr
-structures.
-.IP
-.EX
-struct ifinfomsg {
-    unsigned char  ifi_family; /* AF_UNSPEC */
-    unsigned short ifi_type;   /* Device type */
-    int            ifi_index;  /* Interface index */
-    unsigned int   ifi_flags;  /* Device flags  */
-    unsigned int   ifi_change; /* change mask */
-};
-.EE
-.IP
-.\" FIXME Document ifinfomsg.ifi_type
-.I ifi_flags
-contains the device flags, see
-.BR netdevice (7);
-.I ifi_index
-is the unique interface index
-(since Linux 3.7, it is possible to feed a nonzero value with the
-.B RTM_NEWLINK
-message, thus creating a link with the given
-.IR ifindex );
-.I ifi_change
-is reserved for future use and should be always set to 0xFFFFFFFF.

-Add, remove, or receive information about an IP address associated with

-.I ifa_scope
