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.
Follow-up for ba87a61d05.
Fixes#36997.
Add support for creating HSR/PRP interfaces. HSR (High-availability Seamless
Redundancy) and PRP (Parallel Redundancy Protocol) are two protocols that
provide seamless failover against failure of any single network component. They
are both implemented by the "hsr" kernel driver.
Check that when networkd restarts, and the network configures
KeepConfiguration=yes, the network configuration is never changed.
Ensure this by dumping the `ip monitor` output when networkd is restarting.

Then, we can drop ugly workaround in meson.build.
The .link file is not necessarily synced with 99-default.link.
Also, 99-default.link is not updated so frequently.
Let's manually sync it when necessary.
This fixes some typos in the documentation, both grammar as well as
incorrect field names.
It also changes the casing of CheckSum to Checksum in L2TP to match
other casings.
- Also configures route to the gateway and prefix route in the specified
table, if necessary.
- Also set preferred source address of the route.
Closes#36168.
Since linux commit a35ec8e38cdd1766f29924ca391a01de20163931 ("bridge:
Add MAC Authentication Bypass (MAB) support"), included since v6.2, it
is possible to enable MAC Authentication Bypass for bridge ports. In
this mode the locked port learns again, but the learned fdb entries are
locked, allowing user space to unlock hosts based seen MAC addresses.
This requires learning to be enabled on the port, and link-local
learning disabled for the bridge.
Add support to systemd-network for setting the new attribute for bridge
ports.
Since linux commit a21d9a670d81103db7f788de1a4a4a6e4b891a0b ("net:
bridge: Add support for bridge port in locked mode"), included since
v5.18, it is possible to set bridge ports to locked.
Locked ports do not learn automatically, and discard any traffic from
unknown source MACs. To allow traffic, the userspace authenticator is
expected to create fdb entries for authenticated hosts.
Add support to systemd-network for setting the new attribute for bridge
ports.
When using locked ports on a bridge link-local learning needs to be
disabled to prevent the kernel from learning and automatically unlocking
hosts based on link-local traffic.
So add support for enabling NO_LL_LEARN for bridges.
Add a test for the new bridge netlink attributes IFLA_BR_FDB_N_LEARNED and
IFLA_BR_FDB_MAX_LEARNED.

Due to the bug in kernel 6.9 caused by
8debcf5832,
the net_id udev builtin does not work for netdevsim interface.
So, eni99np1 cannot be used with kernel 6.9 anymore.
Workaround for #32910.
Previously, one of the test route has the same address in destination
and gateway. Even it is a test case, that's super spurious. Let's use a
different address.
