That has a fair number of GUI widgets; Microsoft's Network Monitor does
it with a combo box where the drop-down list has "Full" at the top,
followed by a set of values (it looks like all the multiples of 64, up
to 65472), but it lets you type any value between 1 and 65535 in there. 
That's perhaps a bit less cluttered.  (If you type in a bigger value,
zero, a negative number, or a non-integer value other than "Full", it
puts up a message box telling you that it has to be a number between 1
and 65535; alas, I'm not sure GTK+ 1.0 does a good job of popping up
modal dialog boxes, so that they come out on top and get the input focus
automatically to let you dismiss them with <Enter>/<Return> and type a
better value in.)
