Why the maximum Ethernet frame size is 16,383 bytes in Test Center?

I saw the maximum frame size allowed in Test Center is 16,383 bytes. However, the jumbo frames can be even bigger. I'd like to understand why this figure (16,383 bytes) was chosen. Thanks!

16,383 = 11 1111 1111 1111, in which case 14 bits are currently allocated for the frame size field. If you have a use case that requires a larger frame, you may request for an enhancement.
