Thanks Michal , Could you provide the package you were using ? Case you working on our git , Do you know in which it was broken ? Could you also add more information regarding the driver and device you were using, and the command that you try to execute and caused that clash ?

I found that IB_DEVICE_MR_ALLOCATE is defined as bit 23 for freebsd git hub and accelio github And then I saw there are a lot of clashes between ib_verbs + upstream kernel Clash between the two needs to be resolved. Perftest wise: Perhaps an additional parameter to perftest ?
