Maybe that is why it is not exposed at the disconnect > API call? Would RoCE support it? RoCE and IB have a place to put it, IB does not. The lack of support in iWarp is problematic, these APIs are supposed to be fairly high level things. We clearly can't just extend the existing rdma_disconnect() due to this, and some kind of negotiation would be needed so the ULP can learn if the extra data is supported at all. Jason
