I'm happy to help. So, I look at this: int usnic_ib_post_send(struct ib_qp *ibqp, struct ib_send_wr *wr, struct ib_send_wr **bad_wr) { usnic_dbg("\n"); return -EINVAL; } And conclude that usnic doesn't actually provide any RDMA services to in-kernel users, correct? I'd then guess the entire point of this is to hack some non-RDMA device to export it's interface via uverbs? Presumably because someone nack'd using your own char device or whatever?
