We already set the MAC of OVS interfaces in the ovsdb. Unfortunately,
vswitchd doesn't create the interface with the given MAC from the
beginning, but first creates it with a random MAC and then changes it.
This causes a race condition: as soon as NM sees the new link, it
starts IP configuration on it and (possibly later) vswitchd will
change the MAC.
To avoid this, also set the desired MAC via netlink before starting IP
configuration.

When a user creates a ovs-interface with the same name of the parent
ovs-bridge, openvswitch considers the interface as the "local
interface" [1] and assigns the MAC address of the bridge to the
interface [2].
This is confusing for users, as the cloned MAC property is ignored in
some cases, depending on the ovs-interface name.
Instead, detect when the interface is local and set the MAC from the
ovs-interface connection in the bridge table.

A connection that fails due to dependency-failed is not able to
reconnect until the master connection activates again; when this
happens, the master clears the blocked reason for all its slaves in
activate_slave_connections() and tries to reconnect them. For this to
work, the slave should be marked as blocked when it fails with
dependency-failed.

If the device state change (to disconnected or unmanaged) triggered by
a sleep event happens after the wake, the devices becomes wrongly
unmanaged and it's necessary to manually manage it again, or restart
NM.
During the wake event we should disconnect the device_sleep_cb()
callback for all devices because we don't want to react to state
changes anymore; in particular we don't need to detect when the device
becomes disconnected to unmanage it.

When there are two patch ports connected, each of them must reference
the other; however they can't be created in a single transaction
because they are part of different bridges (so, different
connections). Therefore, the first patch that gets activated will
always fail with "No usable peer $x exists in 'system' datapath" until
the second patch exists.
In theory we could also match the error message, however this doesn't
seem very robust as the message may slightly change in the future.

When the server is restarted the write to unix socket fails with
EPIPE. In such case, don't fail all the calls in queue; instead, after
a sync of the ovsdb state (through a monitor call), start processing
the queue again, including the call that previously failed.
Add a retry counter to avoid that calls are stuck in the queue forever
in a hypothetical scenario in which the write always fails.

If we change the the MTU of an ovs interface only through netlink, the
change could be overridden by ovs-vswitchd at any time when other
interfaces change. Set the MTU also in the ovsdb to prevent such
changes.
Note that if the MTU comes from the connection, we already set the
ovsdb MTU at creation time and so this other update becomes
useless. But it is needed when changing the MTU at runtime (reapply)
or when the MTU comes from a different source (e.g. DHCP).

The ovs-vswitchd.conf.db(5) man page says about the the mtu_request
column in the Interface table:
"Requested MTU (Maximum Transmission Unit) for the interface. A
client can fill this column to change the MTU of an
interface [...] If this is not set and if the interface has
internal type, Open vSwitch will change the MTU to match the
minimum of the other interfaces in the bridge."
Therefore, if the connection specifies a MTU, set it early when adding
the interface to the ovsdb so that it will not be changed to the
minimum of other interfaces.

(cherry picked from commit 990f46505d)
When the ovs interface gets deactivated, it is released from the
master port and we call nm_device_update_from_platform_link (dev,
NULL) to ignore any later event for the interface. This is important
especially because it sets a zero ifindex on the interface and so,
later when the link disappears, we don't unmanage the device but
directly remove it.
However, since ovs commands are queued, the link could appear during
the deactivation and we need to ignore such events. Add a new device
method can_update_from_platform_link() for such purpose.
(cherry picked from commit e9fc1dea43)
(cherry picked from commit c4eb0c6852)
(cherry picked from commit 34a9247a64)
Tracking the deletion of link by ifindex is difficult because the
ifindex of the device is updated through delayed (idle) calls in
NMDevice and so there is the possibility that at a certain time the
device ifindex is not in sync with platform state. It seems simpler to
watch instead the interface name. The ugly thing is that the interface
name can be changed externally, but if users do that on an activating
device they are looking for trouble.
Also change the deactivate code to deal with the scenario where we
already created the interface in the ovsdb but the link didn't show up
yet. To ensure a proper cleanup we must wait that the link appears and
then goes away; however the link may never appear if vswitchd sees
only the last state in ovsdb, and so we must use a ugly timeout to
avoid waiting forever.

(cherry picked from commit 9c49f8a879)
(cherry picked from commit 2e5e409bf2)
(cherry picked from commit 628706fab5)
When we deactivate a virtual device, we usually schedule the deletion
of the link in an idle handler. That action will be executed at a
later time when the device is already in the disconnected state.
Similarly, for ovs interfaces we send the deletion command to the
ovsdb and then proceed to the disconnected state.
However, in the first case there is the guarantee that the link will
be deleted at some point, while for ovs interfaces it may happen that
ovs decides to reuse the same link if there is an addition
queued. Since reusing the same link confuses NM, let's implement
deactivate_async() for ovs-interfaces and wait that the link actually
goes away before proceeding.

When an interface (other OVS device types can not fail) encounters an error
it indicates it by changing the error column. Watch for those changes so

Don't crash in situations, where the bridge or a port has a child with

For ip-tunnel modes that encapsulate layer2 packets (gretap and
ip6gretap) we allow the presence of an ethernet setting in the
connection and honor the cloned-mac-address specified in it.
For all other modes, the ethernet setting is removed during
normalization, but a value different from 'preserve' could be set via
global default.
The kernel doesn't allow setting a MAC for layer3 devices, don't do
it.

The previous code tried to get the bridge active connection and it
used the port active connection instead in case of failure. This
doesn't seem right, as in nm-ovsdb.c the bridge AC is used to get the
bridge settings (including the uuid, interface name, and cloned mac).
In case of failure getting the bridge AC we should just fail.

Surisingly, the compiler may detect the remaining obj_type in
the default switch. Then, inlining nmp_class_from_type() it may detect
that this is only possible to hit with an out or range access to
_nmp_classes array.
Rework the code to avoid that compiler warning. It's either way not
supposed to happen.
Also, drop the default switch case and explicitly list the enum values.
Otherwise it is error prone to forget a switch case.

g_ascii_strtoull() returns a guint64, which is very wrong to directly pass

We try to set only one time the MTU from the connection to not
interfere with manual user changes.
If at some point the parent interface changes temporarily MTU to a
lower value (for example, because the connection was reactivated), the
kernel will also lower the MTU on child interface and we will not
update it ever again.
Add a workaround to this. If we detect that the MTU we want to set
from connection is higher that the allowed one, go into a state where
we follow the parent MTU until it is possible to set again the desired
MTU. This is a bit ugly, but I can't think of any nicer way to do it.

(cherry picked from commit 49857ed279)
A MACsec connection doesn't have an ordering dependency with its
parent connection and so it's possible that the parent gets activated
later and sets a greater MTU than the original one.
It is reasonable and useful to keep the MACsec MTU configured by
default as the maximum allowed by the parent interface, that is the
parent MTU minus the encapsulation overhead (32). The user can of
course override this by setting an explicit value in the
connection. We already do something similar for VLANs.

Introduce a generic function to set a MTU based on parent's one. Also
define a device-specific @mtu_parent_delta value that specifies the
difference from parent MTU that should be set by default. For VLAN it
is zero but other interface types (for example MACsec) require a
positive value due to encapsulation overhead.

Still, the parameter passed to g_signal_emit() is a C string, not a

do anything with the arguments. Though, I am not sure whether glib still
tries to initialize a GValue with a GVariant type, leading to a crash.
