I made some developments with the RXE in the upstream, from my usage with latest RXE, I found the following: 1. rdma-core can not work well with latest RDMA git; 2. There are some problems with rxe in different kernel version; To 2, the commit https://patchwork.kernel.org/project/linux-rdma/patch/20210729220039.18549-3-rpearsonhpe@gmail.com/ can relieve this problem, not sure if some bugs still exist in RXE. To 1, I will continue to make further investigations. So we should have time to make tests, fix bugs and make rxe stable.
