Vincent Haupert 4f442dde0e nixos/networkd: add new options
Systemd 250:

> DHCPv4 client support in systemd-networkd learnt a new Label= option
> for configuring the address label to apply to configure IPv4
> 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
> propagated to the downstream interfaces.

> The [IPv6AcceptRA] section of .network files now understands two new
> settings UseGateway=/UseRoutePrefix= for explicitly configuring
> whether to use the relevant fields from the IPv6 Router Advertisement
> records.

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

> The IgnoreCarrierLoss= setting in the [Network] section of .network
> files now allows a duration to be specified, controlling how long to
> wait before reacting to carrier loss.

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
> by the DHCP lease. A new FallbackLeaseLifetimeSec= setting may be
> used to configure how to process leases that lack a lifetime option.
