With this patch series, there are about 17 errors and 1 failure in rdma-core. " ---------------------------------------------------------------------- Ran 183 tests in 2.130s FAILED (failures=1, errors=17, skipped=124) " After these patches, not sure if rxe can communicate with the physical NICs correctly because of the above errors and failure.
