Thanks for reply. To be more specific, our kernel module depends on the TSS/TSS QP groups, which is in the patch below: https://www.spinics.net/lists/linux-rdma/msg14935.html It's no really about IPOIB and user space. Does upstream support or plan to have that feature? Do you have any suggestion if we want to switch to upstream OFED?
