Previously, the extra stub listners were stopped but new ones were not
started. Also, the main stub listners were not restarted, hence the
new settings were not applied. This fixes the above two issues.
Note, to fix the issue, we need to keep CAP_NET_BIND_SERVICE capability
to make it allow to bind stub listner later.
Fixes#37843.
- set defaults after all existing configs and setups cleared,
- mention failures are ignored in log messages,
- drop one redundant log message,
- do not return negative errno but exit event loop on critical failure.
This also makes ip6tnl can be created without specifying Mode= setting,
as the kernel accepts new-link netlink message without the
IFLA_IPTUN_PROTO attribute.
No effective functional change, just refactoring and preparation for
later change.
We need access to /dev/net/tun, hence make sure we can actually see
/dev/. Also make sure the module is properly loaded before we operate,
given that we run with limit caps. But then again give the CAP_NET_ADMIN
cap, since we need to configure the network tap/tun devices.

The commit cdcb1eeeb8 adds
ID_NET_NAME_INCLUDE_DOMAIN property support in net_id builtin.
The property is basically set through hwdb. However, previously hwdb was
imported after calling net_id builtin, hence when net_id is called, the
property was never set.
This makes hwdb is imported before calling net_id builtin, so that the
property is set when net_id is called if hwdb has an entry about that
for the interface.

BOOTP can be used to sign a static IP to clients. Instead of using the
four message exchange, and Option 53 (DHCP Message Type) there is only a
two message exchange.
Add the following network option to enable BOOTP:
[DHCPv4]
BOOTP=yes
This will allow a two message request / reply sequence that doesn't
require DHCP message types.

Previously, the property was checked only when an uevent is received,
so even if an interface has ID_NET_MANAGED_BY property, the interface
will be configured by networkd when reconfiguration is triggered e.g.
when interface state is changed.
