TFTP packets are structured as follows:

You can see that the total overhead is 46 bytes. If your network port's maximum MTU size is 1500 bytes (the default), the math works out for a maximum TFTP PDU size of 1454 bytes.
However... the Ethernet header/trailer is not supposed to be included in the MTU. I suspect we have a terminology problem here. Let me dig a bit further to find out what's going on.
Hi Ben,
Did you manage to look at this any further?
kind regards, Rafal
