.SH VERSIONS
The socket interface to netlink is a new feature of Linux 2.2.
The socket interface to netlink first appeared Linux 2.2.
Linux 2.0 supported a more primitive device-based netlink interface
(which is still available as a compatibility option).
This obsolete interface is not described here.
NETLINK_SELINUX appeared in Linux 2.6.4.
NETLINK_AUDIT appeared in Linux 2.6.6.
NETLINK_KOBJECT_UEVENT appeared in Linux 2.6.10.
NETLINK_W1 and NETLINK_FIB_LOOKUP appeared in Linux 2.6.13.
NETLINK_INET_DIAG, NETLINK_CONNECTOR and NETLINK_NETFILTER appeared in
Linux 2.6.14.
NETLINK_GENERIC and NETLINK_ISCSI appeared in Linux 2.6.15.
.SH NOTES
It is often better to use netlink via
.I libnetlink
