fb5c821664 networkd: DHCPv6 client allow to configure Rapid Commit (#6930)
The DHCPv6 client can obtain configuration parameters from a
DHCPv6 server through a rapid two-message exchange solicit and reply).
When the rapid commit option is enabled by both the DHCPv6 client and
the DHCPv6 server, the two-message exchange is used, rather than the default
four-method exchange (solicit, advertise, request, and reply). The two-message
exchange provides faster client configuration and is beneficial in environments
in which networks are under a heavy load.

Closes #5845

323d9329e7 networkd: allow to configure default/initial send/recv congestion window and store persistentl (#7750)
Currently we can only change initcwnd/initrwnd in the following way, and it does not store persistently:
sudo ip route change default via 192.168.1.1 dev tun0 initcwnd 20
sudo ip route change default via 192.168.1.1 dev tun0 initrwnd 20

For more details about initcwnd/initrwnd, please look at:

http://www.cdnplanet.com/blog/tune-tcp-initcwnd-for-optimum-performance
or google 'initcwnd initrwnd'

This work allows to configure the initcwnd and initrwnd.

5022f08a23 core,udev,networkd: add ConditionKernelVersion=
This adds a simple condition/assert/match to the service manager, to
udev's .link handling and to networkd, for matching the kernel version
string.

In this version we only do fnmatch() based globbing, but we might want
to extend that to version comparisons later on, if we like, by slightly
extending the syntax with ">=", "<=", ">", "<" and "==" expressions.

22043e4317 networkd: change UseMTU default to true. (#6837)
Typically when DHCP server sets MTU it is a lower one. And a lower than usual
MTU is then thus required on said network to have operational networking. This
makes networkd's dhcp client to work in more similar way to other dhcp-clients
(e.g. isc-dhcp). In particular, in a cloud setting, without this default
instances have resulted in timing out talking to cloud metadata source and
failing to provision.

This does not change this default for the Annonymize code path.

bce67bbee3 networkd: add support to configure IP Rule (#5725)
Routing Policy rule manipulates rules in the routing policy database control the
route selection algorithm.

This work supports to configure Rule
```
[RoutingPolicyRule]

```

```
ip rule show
0:	from all lookup local
0:	from 192.168.100.18 tos 0x08 lookup 7
```

V2 changes:

1. Added logic to handle duplicate rules.
2. If rules are changed or deleted and networkd restarted
   then those are deleted when networkd restarts next time

V3:

1. Add parse_fwmark_fwmask

d6eac9bd06 DHCP: when adding static routes set scopes properly (#5982)
DHCP responses could include static routes, but unfortunately not an
option to tell what scope to use. So it's important that the client sets
it properly.

This mimics what the `ip route add` command does when adding a static
route without an explicit scope:

* If the destination IP is on the local host, use scope `host`
* Otherwise if the gateway IP is null (direct route), use scope `link`
* If anything else, use the current default `global`.

Fixes #5979.

b56be2966a networkd: Add bridge port priority setting (#5545)
Allow setting bridge port priority in the Bridge section of the network file,
similar to e.g. port path cost setting.

Set the default to an invalid value of 128, and only set the port priority when
it's not 128. Unlike e.g. path cost, zero is a valid priority value.

Add a networkd-test.py to check that bridge port priority is correctly set.

Incidently, fix bridge port cost type and document valid ranges.

a0e5c15d4f networkd: add IPv6ProxyNDPAddress support (#5174)
IPv6 Neighbor discovery proxy is the IPv6 equivalent to proxy ARP for IPv4.
It is required when ISPs do not unconditional route IPv6 subnets
to their designated target, but expect neighbor solicitation messages
for every address on a link.

A variable IPv6ProxyNDPAddress= is introduced to the [Network] section,
each representing a IPv6 neighbour proxy entry in the neighbour table.
