Pradeep, Thank you, that works well on one machine. I was able to set the mtu on interface ib1 to 4096 instead of 2044. The max_mtu from ibv_devinfo is still 2048 on port 2. On the other machine, setting the ip mtu fails if I try a number higher than 2044. So which one is the correct behavior? By the way, opensmd is running on the other machine.
I appreciate having the capability to do ip mtu and now have another command in my arsenal. I was hoping to set the IB mtu to 4096 instead of 2048 as shown in the ibv_devinfo. Any ideas on that?
