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?
