+O-Subject: [PATCH RHEL-8.0] IB/rxe: Mark Soft-RoCE Transport driver as tech-preview.
+Bugzilla: 1605216
+RH-Acked-by: Jarod Wilson <jarod@redhat.com>

+
+The Soft-RoCE driver implements the InfiniBand RDMA transport
+over the Linux network stack. 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
