I don't know that the kernel rdma cm code supports this. It's likely that the id would need to have its state reset and data structures cleaned up. That said, I doubt re-use of the rdma_cm_id would provide any real advantage. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
