------- Comment From heinz-werner_se...@de.ibm.com 2021-03-26 05:16 EDT------- SRU Justification:
[Impact] * Since older firmware may not support the uplink state setting, this can lead to problems. * Now expose firmware indication that it supports setting eswitch uplink state to follow the physical link. * <... some more details are needed on how things fail today, w/o the patch> [Fix] * upstream fix (as in 5.11): 9c9be85f6b59d80efe4705109c0396df18d4e11d 9c9be85f6b59 "net/mlx5e: Add missing capability check for uplink follow" https://launchpadlibrarian.net/529543695/0001-Backport-net-mlx5e-Add- missing-capability-check-for-.patch * backport for groovy: https://launchpadlibrarian.net/529775887/0001-Backport-groovy-net-mlx5e-Add-missing-capability-che.patch [Test Case] * It requires an IBM Z or LinuxONE system, with groovy/focal installed in LPAR and RoCE Express 2.x adapters attached. * Due to the lack of hardware this needs to be verifid by IBM. [Regression Potential] * This backport fixes a regression which was introduced with the kernel 5.4.0-48 update for Ubuntu 20.04. [Other] * The above patch/commit was upstream accepted with kernel 5.11. * Hence the patch is not needed for hirsute, just SRUs for groovy and focal are needed. * But the commit couldn't be cleanly cherry-picked, due to changed context, hence the backport(s). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1921104 Title: net/mlx5e: Add missing capability check for uplink follow for Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1921104/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
