This seems surprising to me.. Hi Jason, Last time I checked the Mellanox drivers allow MADs to be sent over a SR-IOV VF but do not allow MADs to be received through such a VF. I haven't been able to find any reference to management datagrams in the iWARP RFC. Maybe that means that I overlooked something? Thanks, Bart.
