[c-nsp] Counters for null0?

[luismi]

I just configure a router here to use it but it is quite strange because
I can see correct traffic routed to "null", and I didn't expect to see
that, I don't think it is correct.

#sho ip cache flow | incl Null
Fa0/1.1       10.55.0.32      Null          208.67.222.222  11 0A2A 0035

Fa0/1.1       10.55.0.32      Null          208.67.222.222  11 0A26 0035

208.67.222.222 is the opendns server but the destination interface is
"null"

Any idea why I see that? is that correct (I don't think so)?
