It enables a system with a +standard Ethernet adapter to interoperate with a RoCE +adapter or with another system running the RXE driver. + +Unfortunately, a wide range of tests and/or use-cases have shown +that the driver is not ready for enterprise use, and upstream bug +fixing may not be complete for RHEL-8.0. +Thus, recommendation from driver maintainer is to mark it as +tech-preview. It is expected that future bug fixes will enable it +to be upgraded to fully supported. In the mean time, it works +in a number of use cases, and can be used to demonstrate upstream +fixes on failing cases. + +Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1605216 +Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=17344161 + +Testing: +Simple boot test, and loading of rxe driver to show tech-preview +msg is generated in dmesg log. + +Upstream Status: RHEL only +Signed-off-by: Donald Dutile <ddutile@redhat.com +Signed-off-by: Herton R.
