<p>Hello Roland, Michael,<br>
<br>
I tried GSO for IPoIB last year, I didn't see much BW for UD rather than some cpu utilization decreasement. I looked the GSO patch carefully then I found there are additional skb copies in skb segment. If the device supports SG, then the copies can be avoided. IPoIB does support SG, I am planning to enable it to test GSO again. I would like to know whether you have tried this before? Any possible issue you can think of?<br>
<br>
Thanks<br>
