| H A D | intro.rst | 4 Introduction to Netlink
7 Netlink is often described as an ioctl() replacement.
12 To achieve this Netlink uses a minimal fixed-format metadata header
18 netlink as it is used today and dives into more "historical" uses
24 Netlink communication happens over sockets, a socket needs to be
36 A very simplified flow of a Netlink "call" will therefore look
48 Netlink also provides natural support for "dumping", i.e. communicating
70 it is opening a Netlink socket, with all headers provided by the user
71 (hence NETLINK, RAW). The last argument is the protocol within Netlink.

14 The netlink-raw schema extends the :doc:`genetlink-legacy <genetlink-legacy>`
16 multicast IDs used by raw netlink families. See :ref:`classic_netlink` for more
17 information. The raw netlink families also make use of type-specific

10 hand written Netlink code for each new family, command, attribute.
