STLFlowStats vs STLFlowLatencyStats and update stream

[Marc Viola]

Hi,

Using linux interfaces.  I'm creating a stream using the following:

streams.append(STLStream(packet = STLPktBuilder(base_pkt/random_string), mode = STLTXCont(bps_L2 = bitrate*1000),flow_stats = STLFlowLatencyStats(i)))

When I try to update the stream with:

c.update(ports=port_0,mult=str(bitrate)+'kbps',force=True)

Not only the bitrate doesn't change but sometimes I get the following error:

Port 0 : *** current stream configuration enforces a minimum rate of '965000' BPS L2

I figured there would be a unit calculation problem but if I replace STLFlowLatencyStats with STLFlowStats then the rate chages.  Is there any reason the Latency function wouldn't work in this case?  Is it a side effect of the interface not being supported or something?

Thanks.
