All the point-to-point interfaces don't have a MAC address.
You don't need it since there is only one place
to which you can write data, into the port. 

Well, the problems start when you want to establish 
X.25 connections. Then you use the X.25 address similarly
to a MAC address. But since usually the X.25 connections
are static, you set up your table of connections
and the translation table between the target IP
address and X.25 address, similar to ARP but static.
