| 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

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

7 Netlink protocol specifications are complete, machine readable descriptions of
8 Netlink protocols written in YAML. The goal of the specifications is to allow
9 separating Netlink parsing from user space logic and minimize the amount of
10 hand written Netlink code for each new family, command, attribute.
11 Netlink specs should be complete and not depend on any other spec
22 YAML specifications can be found under ``Documentation/netlink/specs/``
34 There are four schema levels for Netlink specs, from the simplest used
