Simon,

Since I also performed testing on the previous patchset, I'll share what I did.

I configured Network Manager to use the TBT interface to share an internet
connection to another box.  This configures a static IP address on the local
Linux side and sets up routing.

Network manager remembers setup this in a configuration database.  
When the interface goes up it will then set up a DHCP server to hand
out an IP address to the other side.
