I agree with you. I believe simple rping still doesn't work linux-to-linux. The last working version (of rping in rxe) was 5.13 I think. I have posted a number of crashes rping encounters (gotta get that working before I can even try NFSoRDMA). Thank you for working on the code. We (NFS community) do test NFSoRDMA every git pull using rxe and siw but lately have been encountering problems. > rdma-core: > 313509f8 (HEAD -> master, origin/master, origin/HEAD) Merge pull > request #1038 from selvintxavier/master > 2d3dc48b Merge pull request #1039 from amzn/pyverbs-mac-fix-pr > 327d45e0 tests: Add missing MAC element to args list > 66aba73d bnxt_re/lib: Move hardware queue to 16B aligned indices > 8754fb51 bnxt_re/lib: Use separate indices for shadow queue > be4d8abf bnxt_re/lib: add a function to initialize software queue > > kernel rdma: > 0050a57638ca (HEAD -> for-next, origin/for-next, origin/HEAD) > RDMA/qedr: Improve error logs for rdma_alloc_tid error return > 090473004b02 RDMA/qed: Use accurate error num in qed_cxt_dynamic_ilt_alloc > 991c4274dc17 RDMA/hfi1: Fix typo in comments > 8d7e415d5561 docs: Fix infiniband uverbs minor number > bbafcbc2b1c9 RDMA/iwpm: Rely on the rdma_nl_[un]register() to ensure > that requests are valid > bdb0e4e3ff19 RDMA/iwpm: Remove not-needed reference counting > e677b72a0647 RDMA/iwcm: Release resources if iw_cm module initialization fails > a0293eb24936 RDMA/hfi1: Convert from atomic_t to refcount_t on > hfi1_devdata->user_refcount > > with the above kernel and rdma-core, the following messages will appear. > " > [ 54.214608] rdma_rxe: loaded > [ 54.217089] infiniband rxe0: set active > [ 54.217101] infiniband rxe0: added enp0s8 > [ 167.623200] rdma_rxe: cqe(32768) > max_cqe(32767) > [ 167.645590] rdma_rxe: cqe(1) < current #
