The two attributes "Tunnel-Type (64)" and "Tunnel-Medium-Type (65)" are particularly special. The value type of them is an integer and this is also signaled via REST, but the value provided is the string representation of the integer.

  I've pushed a fix for v3.0.x.  It always prints the integer value, and does not print the name.
