[openib-general] Multiple IPoIB devices over same port

> a separate Qos tag is used for each stream?

Sorry for the late response. You could do that. I just list some possible 
uses of Multiple IPoIB devices over same port. Other reasons could be 
different MTUs or other interfaces characteristics.. Basically there is no 
reason to restrict this implementation.

Thanks

I am not sure I follow. Do you mean that for example, a separate Qos tag 
is used for each stream? If this is the case I am not sure how to handle 
Qos tags from the VM.
 

I thought about this so that at a higher level you can use policy routing 
or QoS or traffic shapping or maybe even CKRM to distribute load on 
multiple streams.
