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.
Indeed, we got reports of some Cisco switches dropping DHCP packets
because of the CS6 marking.
For these reasons, change the default value to the recommended one,
CS0.
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.
The client currently always sets the DSCP value in the DS field
(formerly known as "TOS") to CS6. Some network equipment drops packets
with such DSCP value; provide a way to change it.
This commit introduces the display of the global metered state in the
`nmcli general` command output.

Previously, input fields for peer attributes such as 'Public Key' were
not pre-populated with the existing settings of the peer. This was due
to the WireGuard peer editor class not setting its peer property during
object construction, as the necessary flag was absent. This commit
addresses and fixes this issue.

In order to make _nm_setting_property_define_direct_enum more flexible,
this patch is introducing property_type argument to it. When set to NULL
it will set property_type to nm_sett_info_propert_type_direct_enum.
Defining the wrong from_dbus/to_dbus functions is something not
probable. The unit test is just getting in the way of those who knows
what they do and force contributors to change the same thing in multiple
places.
It's simply not valid to read the ref-count without an atomic.
The compiler might optimize out the assignment to "r" and read the
_ref_count field multiple times. Thereby, we might at first appear
to be larger than > 1, and later pass 1 to compare-and-exchange.
We need an atomic get here.

This property indicates that a non-null strv array is expected, and
an empty strv array should be returned instead of NULL if it hadn't
been created yet.
The comparison checking for MAC address equality had previously been flipped around.

The default in systemd-resolved is nowadays "yes". In any case, since
the setting is configurable systemd-resolved, don't describe it in the
manual page.
Instead, clarify the behavior and try to improve the documentation.

As done for IPv4 in commit 3b145a33b7 ('vpn-connections: allow the
plugin to specify route preferred src'), allow VPN plugins to return a
preferred source address for routes. Still accept the old format.
OpenShift MetalLB team requests to configure additional routes
whenever the nodes does not have a configured IP address or route for
the subnet in which MetalLB issues addresses.
Note in linux network stack, it does not matter what interface you add
the address on a node (for example, loopback), the kernel is always
processing arp-requests and sending arp-replies to any of them, this
behavior is considered correct and, moreover, it is widely used in the a
dynamic environment as Kubernetes.

The decision to configure or not configure routes without addresses only
related to what method is configured - DHCP and non-DHCP cases. For DHCP
case, the deamon waits until addresses appear first before configuring
the static routes to preserve the behavior mentioned in
https://bugzilla.redhat.com/show_bug.cgi?id=2102212, otherwise, the
daemon can configure the routes immediately for non-DHCP case.
"nm_setting_hsr_get_port1" is new API and verify() already enforces that
the strings are not empty. The flag is redundant.
Also drop it from a few other places, where it's redundant.
