I checked the repo you post,

1) package config 'networkd' and 'resolved' have been involved in 
default package config in systemd_242.bb

2) I suspect wireless.network is not necessary. Unlike wired network, we 
can't predict the ap name and connect it automatically.

3) the configure file doesn't work with qemu tap mode. I'll update with it.

4) Do the configure of section [DHCP] in wired.network necessary?

[DHCP]
RouteMetric=10
ClientIdentifier=mac


Thanks.
