See "man interfaces".  According to that manual page, all you need is to
find the relative line for the desired interface in
"/etc/network/interfaces" and directly append a line in the form of "mtu
_size_", where _size_ is the number you want it to be fixed at, of
course.

If that doesn't help, please re-post here again.  (Also, you might want
to explain more on what exactly you want to do.)
