I need to give XRC support to the librdmacm more thought, but here are at least the initial concerns: - XRC support upstream (kernel and user space) is still pending. (I can start a librdmacm branch for XRC support.) - Changes are needed to the kernel rdma_cm. We could start submitting patches against Roland's xrc branch for these. - Please update to the latest librdmacm tree. More specifically, rdma_getaddrinfo should support XRC as well. In general, I'd like to find a way to add XRC support to the librdmacm that makes things as simple for the user as possible. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
