CEF in general breaks weird and interesting things.

In a "normal" router all should be ok.

We have a situation where CEF in a particilar 12.0.x version broke the BVI
interface in an IRB configuration w/ATM.   Then the next version broke
forwarding between an ATM interface and a Ethernet interface in an
interesting way (I haven't tracked down the specifics on the second case
yet.)

All in all, CEF works wonders, if it doesn't break something with its
extra-fancy forwarding.
