yes. i wrote tpmr for this exact situation. i wanted to connect switches in different datacentres together over tunnels (etherip in my case) while i was migrating from one site to the other. i was considering calling the driver xconnect or xcon, but went with tpmr because i was reading the ethernet bridge specification at the time and it talks about a special type of bridge called a two port mac relay.
