O-Subject: [PATCH RHEL-8.0] IB/rxe: Mark Soft-RoCE Transport driver as tech-preview.
Bugzilla: 1605216

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.
