mouse-pppoe sets an MTU of 1400 on the ppp0 interface.  Should I be able
to safely lower the MTU (of my ethernet) while my network is live, if I'm
careful/lucky?  (I assumed that I could, but when I tried the second
machine that I lowered (my gateway) crashed to the extent that it wouldn't
even respond to ping...)
