Currently the internal DHCP client sets traffic class "CS6" in the DS
field of the IP header for outgoing packets.
dhclient sets the field according to the definition of TOS (RFC 1349),
which was was deprecated in 1998 by RFC 2474 in favor of DSCP.
Introduce a new property IPvX.dhcp-dscp (currently valid only for
IPv4) to specify a custom DSCP value for DHCP backends that support it
(currently, only the internal one).
Define the default value to CS0, because:
- section 4.9 of RFC 4594 specifies that DHCP should use the standard
(CS0 = 0) service class;
- section 3.2 says that class CS6 is for "transmitting packets
between network devices (routers) that require control (routing)
information to be exchanged between nodes", listing "OSPF, BGP,
ISIS, RIP" as examples of such traffic. Furthermore, it says that:
User traffic is not allowed to use this service class. By user
traffic, we mean packet flows that originate from user-controlled
end points that are connected to the network.
- we got reports of some Cisco switches dropping DHCP packets because
of the CS6 marking.

libnm-core-public
This contains (mostly) header files only, which are also part of
the public API of libnm.
Also, this API is implemented by the static library libnm-core-impl,
which in turn is statically linked into NetworkManager core and libnm.
These headers can be used by anybody who either:
- links (statically) against
libnm-core-impl. - links dynamically against
libnm.
Note that there is also one source file: nm-core-enum-types.c.
This source file really belongs to libnm-core-impl but it is here
because it's a generated file and so far I couldn't figure out how
to generate nm-core-enum-types.h here while moving nm-core-enum-types.c
to libnm-core-impl.
Aside nm-core-enum-types.c, this directory only provides header files.
Users should add this directory (both srcdir and builddir) to the include
search path, because libnm users are used to include these headers unqualified
(like #include "nm-setting.h).
