2 @subsection Maximum Transmission Unit
4 MTU option tells what maximum transmission unit is expected to get from
5 TAP interface. It is per-user configuration. Incoming packets of bigger
6 sizes (including the padding byte) will be ignored. If either
7 @ref{Noise, noise}, or @ref{CPR} are enabled, then all outgoing packets
8 are filled up to that MTU value.
10 Default MTU equals to 1514 bytes (1500 bytes of Ethernet payload, 14
11 bytes of Ethernet header).
