      Description

      When filtering flows by SNMP interface we currently match the associated ifIndex in the netflow.input_snmp field.

      Unless all of the traffic goes in and out this same interface, this can give incorrect values, since we should be scoping the interface by direction as well.

      Current query: input_snmp == ifIndex
      Revised query: (direction == 'ingress' && input_snmp == ifIndex) || (direction == 'egress' && output_snmp == ifIndex)
