	Yep the Cidr version works correctly, but that appears to preclude 
odd things like this (that works on 2.0.6)

which selects traffic to all of our routers (which are on the .254 address
of each subnet) which is sometimes useful. 
	While I'm here we have just built a 2.6.18 Linux kernel with the 
PF-RING code installed and so far it looks more stable than the previous 
versions. It had been going out sideways somewhere and completely hanging the
machine (no console no nothing, power cycle time!) so if this happy state of
affairs continues I should be able to get 3.0 running in parallel with my
current 2.06 sensor on the regen taps on our border. If you are using PF-RING
this may be worth a look (although there are reports of packet corruption on
the mailing list too).
