 default on all other face types.
 Parameters for this feature can set with the **congestion-marking-interval** option (specified in
 milliseconds) and the **default-congestion-threshold** option (specified in bytes).
+The MTUs of unicast Ethernet and UDP faces may be overridden using the **mtu** parameter (specified
+in bytes).
+However, a face may choose to limit the range of acceptable values for this parameter or disregard
+it altogether when setting its MTU.
+The MTU of an existing face may not be modified using this parameter and will result in an error.
 
 The **nfdc face destroy** command destroys an existing face.
