MTU option tells what maximum transmission unit is expected to get from
TAP interface. It is per-user configuration. Incoming packets of bigger
sizes (including the padding byte) will be ignored. If either
-@ref{Noise, noise}, or @ref{CPR} are enabled, then all outgoing packets
-are filled up to that MTU value.
+@ref{Noise, noise}, @ref{Encless, encryptionless mode} or @ref{CPR} are
+enabled, then all outgoing packets are filled up to that MTU value.
-Default MTU equals to 1514 bytes (1500 bytes of Ethernet payload, 14
