我一直在尝试使 krring 模块工作，可以在这里找到：http ://git.openfabrics.org/?p=~sgrimberg/krping.git;a=summary
[ 446.242534] rdma_krping: Unknown symbol ib_alloc_fast_reg_page_list (err -22)
[ 446.242542] rdma_krping: disagrees about version of symbol rdma_resolve_addr
[ 446.242542] rdma_krping: Unknown symbol rdma_resolve_addr (err -22)
[ 446.242549] rdma_krping: disagrees about version of symbol ib_reg_phys_mr
**and so on...**
我通过 Mellanox ofed kernel 3.3 安装驱动程序。已经从 ofa-kernel/default 复制了 Module.symvers 但它不起作用。
我已经在 ubuntu 12.04 和 14.04 的不同内核上尝试过它。我使用的内核是 3.18、3.5 和 4.0。但是，每次我遇到同样的问题。如果有人编译了 krping 并且可以帮助解决这个问题？特别是内核版本、操作系统和安装他们使用的驱动程序的过程。

以上是我尝试编译模块的两个makefile。建议我可以尝试的任何更改。
