These don't explain the history of the 1518 bytes, but it's pretty good
along those lines -

Subject: Mtu ethernet

Hi, 

Can someone tell me why the mtu is 1500 on ethernet. Where does this
number come from.. Or how is it worked out. 

I cant believe I still don't know this having reached CCIE and all. I
dread the day some grad asks me and I have to say I don't know

I have searched the web but can find the specific answer of why 1500.. 

Any help appreciated. 

Thanks
