我在 Ubuntu 16.04 上使用 Mellanox 提供的最新 OFED 包时遇到了 NFS over RoCE 问题（MLNX_OFED_LINUX-3.3-1.0.4.0-ubuntu16.04-x86_64.tgz）。我的卡是 Mellanox 10Gbe，并且启用了 RoCE v1。
适用于 Inbox 驱动程序/软件，但不太适用于最新的 OFED
我按照此网站上的文档，使用 Inbox 驱动程序/软件（包含在 Ubuntu 16.04 中），设法使 NFS 与 RoCE 配合使用。我遇到了一些小问题，而且我知道 Ubuntu 的东西已经过时了，所以我想安装最新的 OFED/mlx4 驱动程序等... 按照 mellanox.com 上的建议。所以我这样做了。一切都按计划进行。IP 功能都在那里，RDMA 工具/测试都正常工作。一切似乎都运行良好。除了一件事。
svcrdma 和 xprtrdma 模块将不会加载。因此，对我来说，NFS 不支持 RDMA。我收到以下错误。如果我仅从 Mellanox 网站安装最新的 mlx4 驱动程序，而不安装其他软件包，也会收到同样的错误。
我感觉这个问题可以通过某种方式解决 - 比如通过重新编译内核模块等，但目前我还没搞明白。或者我只是把事情搞砸了（祈祷好运）？有人能帮忙吗？
有人评论在 Mellanox 社区的这篇文章中Ubuntu 14.04 有同样的问题：https://community.mellanox.com/docs/DOC-2132 根据同一文档，它应该可以与 CentOS 7 一起正常运行。有什么区别？
我想要的最终结果是让最新的驱动程序和软件（最好）在 Ubuntu 16.04 上使用 NFS over RoCE。如果不是最新的 OFED 软件包，至少也要有最新的 mlx4 驱动程序。我读到过一些文章说较新的内核版本将具有更新的驱动程序和 RDMA 代码（我忘记了大部分内容）。如果这无济于事，我的答案可能是等待较新的 Ubuntu 版本。
谢谢
