|
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.

|
Simple boot test, and loading of rxe driver to show tech-preview
|
|
|
|
|
msg is generated in dmesg log.
