Systemd 250:
> DHCPv4 client support in systemd-networkd learnt a new Label= option

> addresses.
> The [IPv6AcceptRA] section of .network files gained support for a new
> UseMTU= setting that may be used to control whether to apply the
> announced MTU settings to the local interface.
> The [DHCPv4] section in .network file gained a new Use6RD= boolean
> setting to control whether the DHCPv4 client request and process the
> DHCP 6RD option.
> The [DHCPv6] section in .network file gained a new setting
> UseDelegatedPrefix= to control whether the delegated prefixes will be

> The [IPv6AcceptRA] section of .network files now understands two new
> settings UseGateway=/UseRoutePrefix= for explicitly configuring

> The [RoutingPolicyRule] section of .network file gained a new

Systemd 246:
> systemd-networkd's [DHCPv4] section gained a new setting UseGateway=
> which may be used to turn off use of the gateway information provided

> used to configure how to process leases that lack a lifetime option.
> The IPv6Token= section in the [Network] section is deprecated, and

>> The Token= setting gained 'eui64' mode to explicitly configure an

* Remove `ForceDHCPv6PDOtherInformation=`
* Add a missing `WithoutRA=` option
Systemd 250:

Adapt to changes introduced in Systemd 250:
> The [DHCPv6PrefixDelegation] section in .network file is renamed to
> [DHCPPrefixDelegation], as now the prefix delegation is also
> supported with DHCPv4 protocol by enabling the Use6RD= setting.
Replaces the `dhcpV6PrefixDelegationConfig` with
`dhcpPrefixDelegationConfig` and throws an error if the old option is
used.
Also adapt the respective IPv6 prefix delegation test.
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
mostly no rendering changes. some lists (like simplelist) don't have an
exact translation to markdown, so we use a comma-separated list of
literals instead.
most of the screen tags used in option docs are actually listings of
some sort. nsd had a notable exception where its screen usage was pretty
much a raw markdown block that made most sense to convert into docbook lists.
the way these are written they introduce lots of whitespace in each
line, which will cause those lines to render as code when converted to
markdown. override the whole description instead.
