Hi Robert, AFAIK, MLNX_OFED does includes isert only for specific distros. This is probably a compat issue between stock isert and MLNX provided RDMA stack. Any specific reason not to use upstream (or stock 4.4.27) kernel? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
