[c-nsp] Netflow Top Talkers?

Hi,

(I agree to your other post regarding "overall effort" - yes, if you
bring a netflow collector into the picture, netflow is more effort)

More recent IOSes permit to set "ip flow ingress" instead of 
"ip route-cache flow" - and "ip flow ingress" can be enabled on 
individual sub-interfaces.

It does not actually *do* anything different as far as I know (as there 
is no forwarding path "netflow switching" anymore), but still, it's two 
different commands, not just an alias "old style / new style".

I'm not exactly sure anymore at what time "ip flow ingress" appeared,
but it's certainly in 12.2S and 12.3.
