  Maximum Transmission Unit
  MTU
  
     <networking> (MTU) The largest number of bytes of "payload"
     data a frame can carry, not counting the frame's header
     and trailer.
  
     A frame is a single unit of transportation on the data link layer
     .  It consists of header data plus data which was passed
     down from the network layer (e.g. an IP datagram) plus
     sometimes trailer data.
  
     An Ethernet (V2) frame has a MTU of 1500 bytes but the size of
     the frame can be up to 1526 bytes (22 byte header, 4 byte CRC
     trailer).
  
     See also fragmentation.
