You say: "MTU is Maximum Transmission Unit including the Ethernet
Encapsulation The data size is determined by MSS or Maximum Segment Size"

Well, this is an excerpt from your link:

Standard Ethernet frame MTU is 1500 bytes. This *does not include *the
Ethernet header and Cyclic Redundancy Check (CRC) trailer, which is 18 bytes
in length, to make the total Ethernet frame size of 1518. In this document,
MTU size or packet size refers only to Ethernet payload. Ethernet frame size
refers to the whole Ethernet frame, including the header and the trailer.
Baby giant frames refer to Ethernet frame size up to 1600 bytes, and jumbo
frame refers to Ethernet frame size up to 9216 bytes.

Anyways, Bit, you get the idea I am sure.
