	Oops, I missed.  I'm testing until following level.
	# ngctl mkpeer . eiface if_ngeth ether
	# ngctl mkpeer ngeth0: atmllc lower ether
	# ngctl list
	There are 6 total nodes:
	  Name: ngctl1269       Type: socket          ID: 0000000f   Num hooks: 0
	  Name: <unnamed>       Type: atmllc          ID: 0000000a   Num hooks: 1
	  Name: ngeth0          Type: ether           ID: 00000007   Num hooks: 1
	  Name: <unnamed>       Type: eiface          ID: 00000006   Num hooks: 0
	  Name: iwi0            Type: ether           ID: 00000003   Num hooks: 0
	  Name: rl0             Type: ether           ID: 00000002   Num hooks: 0

	I have no idea to connect ngeth0 <-> rl0.
