[nsp] How do I disable layer3 processing on a cat6k or cat4k that are i n layer 2 mode?

[Don Bowman]

I have a cat6k (running hybrid), and a cat4k (running IOS).
Both are being used in layer2 mode.

I would like to be able to send packets through that are
IP, but have errors in the IP header (its a test lab).
e.g. bad ip checksum, bad ip length, etc. These are addressed
with ethernet mac learning only.

I'm finding these are dropped by the switch, but no counter
seems to go up.

Does anyone have any suggestions?
