[netflow-tools] Softflowd not recognizing interface index

I've dropped pfflowd to try out softflowd as it appears to be a bit 
more "compliant" than the pfflowd exports.  However, I notice that my 
flows still don't seem to be reporting the correct index numbers for 
the interfaces.  I'm not very SNMP savvy, so perhaps it's my own 
inexperience showing.  Can someone please explain to me why the 
following output all have 0 as the if_index_in and if_index_out for all 


A good example is seen on lines 1-2 and 8-9.  Each pair represents the 
same SSH session but they appear to come from different softflowd 
agents (first from the external interface, then the internal).  
Regardless, they all report an if_index_* of 0, no matter the direction 
or agent.
