Try printing the entire structure and see if any of the fields near conn_tcp look like pointers that might be conn_t's. A while ago, I found the conn_t (or similar field) was where the conn_dev (or similar field) should be. You can try using address::whatis for pointers near the conn_tcp field to see if any of them are coming from a conn related cache.
