iproute: re-route unknown keys into queue 0
ipdb: dotkeys class + transaction model

 * access atributes in both ways:
	ip['eth0']['address']
	ip.eth0.address
 * transaction model: change interface attributes and later commit them:
	ip.eth0.address = '00:11:22:33:44:55'
	ip.eth0.ifname = 'network'
	ip.eth0.commit
	( eth0 → network)
	ip.network
