convert network link/address to module-based-service ... and make bridge use it. We also had to convert bridge back into a pair of services. Downstreams want to depend on the bridge it self being configured even if not necessarily all the members are up. e.g. don't want to break ssh on lan if there's a misconfigured wlan device

support setting network device names this means that net devices in devices/foo/default.nix can be specified by their sysfs paths (instead of by "eth0" and "eth1" that may change from one kernel version to the next) and given mnenomic names that are helpful for the hardware. Like "wan" and "lan[1..4]"
