From d2c872001eff1b482ccecbb11fdac1d9fff1491f Mon Sep 17 00:00:00 2001 From: Don Dutile Date: Tue, 24 Jul 2018 22:29:16 -0400 Subject: [PATCH] IB/rxe: Mark Soft-RoCE Transport driver as tech-preview Message-id: <20180724222916.19362-1-ddutile@redhat.com> Patchwork-id: 225418 O-Subject: [PATCH RHEL-8.0] IB/rxe: Mark Soft-RoCE Transport driver as tech-preview. Bugzilla: 1605216 RH-Acked-by: Jarod Wilson RH-Acked-by: Jonathan Toppins RH-Acked-by: Tony Camuso RH-Acked-by: Honggang Li 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.
