ipForwarding should work fine.  it _should_ change behavior based on 
whether there are any L3 interfaces configured or not.

the challenge is how to use this moving forward on Cisco platforms that 
have dedicated out-of-band management interfaces (e.g. Nexus platforms), 
because technically speaking, they ALWAYS have at L3 interface 
configured (mgmt0 out-of-band) which is L3 by definition because it 
exists in its own 'management' VRF).

its one case where the MIB falls down & is showing its age.
in the case of Nexus, we're thinking about 'lying' in the ipForwarding 
answer to exclude 'management VRF' but even so . . .
