[package] base-files:

	- add aliases to device by default (not ifname)
	- introduce option "layer" to select the target ifname to attach the alias to:
		- 3 use tun device (tun over bridge over device) fallback to bridge or device
		- 2 use bridge (bridge over device) fallback to device
		- 1 use device
