It's intrinsically used when building manpages, and also part of the
introspection-specific parts of the documentation build. There's no
particular guarantee either of those will actually be invoked during a
build, so don't unconditionally look it up.
This allows building with one fewer dependency in many cases.
The Open VSwitch interfaces have corresponding platform links. When an
Open VSwitch interface is created while NetworkManager is running, the
OVS factory usually sees an OVSDB entry appear first, then creates a
NMDevice. After that, when a platform link appears, the device is
already there.
Upon a (re-)start, the link might be seen first, and then things
go south. The OVS factory rejects the device, which results in Generic
device being created instead. Another device, this time of an
appropriate is created for the same link once the OVSDB entry is seen.
Needless to say, with two NMDevices for the same platform link existing,
no end of mayhem ensues (an assertion is tripped).

A device has the "external-down" unmanaged flag when:
!is-created-by-nm AND (!is-up OR (!has-address AND !is-controller))
When the "is-up" or the "has-address" conditions change, we properly update
the unmanaged flag by calling _dev_unmanaged_check_external_down() in
_dev_l3_cfg_notify_cb(PLATFORM_CHANGE_ON_IDLE).
The "is-controller" condition changes when another link indicates the
current device as controller. We currently don't update the unmanaged flag
when that happens and so it's possible that the device stays unmanaged even
if it has a port. This can be easily reproduced by running this commands:
ip link add veth0 type veth peer name veth1
ip link add vrf0 type vrf table 10
ip link set vrf0 up
ip link set veth0 master vrf0
Sometimes, the device shows as "unmanaged" instead of "connected
(externally)".
Fix this by re-evaluating the "external-down" unmanaged flags on the
controller when a port is attached or detached.

When calling to nm_device_is_available, the device types that requires a
parent like VLAN or MACVLAN checks that their parent exists.
nm_device_is_available is a function to check if the device is available
to activate a connection, so it makes sense that if the parent is not
present it can't be activated.
However, this is wrong for 2 reasons:
1. Most of they are virtual devices that might be unrealized when
checking its availability. If they're unrealized, their parent hasn't
been set yet.
2. Even if they're realized, their current parent might not be the one
that is defined in the connection that is being activated.
This is causing that unrealized devices are not being activated as ports
because nm_manager_get_best_device_for_connection thinks that they are
not available.
Get rid of these checks for the parent in the is_available callbacks.

When defining an IPv6 address with square brackets and prefix, like
[dead::beef]/64, the prefix was silently ignored. The address was
accepted only accidentally, because get_word replaced ']' with '\0' so
it resulted in a valid IPv6 address string, but without the prefix.
The previous commit has fixed get_word with better logic to handle the
square brackets, uncovering this issue.
Fix it by explicitly splitting IP addresses and prefixes in
reader_parse_ip so we get a valid address and prefix.
Also, use a prefix different to 64 in the test test_if_ip6_manual. 64 is
the default one, making that the test passed despite the defined prefix
was actually ignored.

If any bond option contains an IPv6 address it needs to be enclosed with
[]. Otherwise the ':' separators from the IP address can be confused
with the ':' separators from the 'bond=' cmdline arguments.
However, the square brackets were ignored:
$ nm-initrd-generator -s "bond=bond0:eth0,eth1:ns_ip6_target=[FC08::789:1:0:0:3]"
NetworkManager-Message: 08:46:55.114: <warn> [1745498815.1146] cmdline-reader: Ignoring invalid bond option: "ns_ip6_target" = "[FC08": '[FC08' is not a valid IPv6 address for 'ns_ip6_target' option
NetworkManager-Message: 08:46:55.114: <warn> [1745498815.1148] cmdline-reader: Ignoring extra: '789:1:0:0:3]'.
The opening '[' was only being considered if it was the first character
in `get_word`. Fix it and consider it if it's in the middle too.
If the brackets are used first and last, directly remove them as it is what
most callers expect. However, if it's in the middle there is no reasonable
way to remove them, so don't do it. Instead, the caller will have to consider
this possibility when processing the content.

NMDevices have a special "can_reapply_change_ovs_external_ids" boolean
field indicating whether the device type supports reapplying the
ovs-external-ids and ovs-other-config settings.
Remove this field and use the standard can_reapply_change() method. No
change in behavior is expected.
If a OVS bridge created via NM has a port created externally, when the
bridge connections goes down then NM detaches the NM-created
port. However, it finds that the bridge still has a port (the external
one) and so it doesn't remove the bridge from ovsdb.
This is a problem, because it means that an explicity deactivation of
the bridge leaves the bridge up. To fix this, only track the number of
port in the bridge actually created by NM. Also, leave alone bridges
not created by NM.
Skip the internal NBFT table parsing when nbft interfaces

As suggested during the review process, NBFT is niche and most users
won't need it. So keep the initrd generator light and only open
libnvme when any NBFT table is found.
In a typical dracut host-only scenario the nbft dracut module will
be pulled in only when NBFT is present in the system, packing in
nvme-cli and libnvme in the initramfs image.

The NVMe Boot Firmware Table (NBFT) is a mechanism of passing context
from a pre-OS Boot environment to an OS runtime, as defined by the
NVM Express Boot Specification. Exposed as an ACPI table it contains
network interface definitions along with NVMe subsystem and namespace
data structures.
This adds new nm-initrd-generator parser that uses libnvme NBFT parser
implementation.

We often forget to add new files to POTFILES, and also
have some paths in the skip file that have not existed
for 15+ years. We should ensure that these files include
the paths that should be there, and nothing more.
This commit adds a test that checks whether all the files
in the po lists exist, and vice versa, that all the files
in the source tree that should be included in this list,
are indeed included in this list.
