[Kernel-packages] [Bug 1925452] Re: [Ubuntu 21.04] net/mlx5: Fix HW spec violation configuring uplink
I just checked the situation for this on hirsute. The patch is already included in hirsute (master): da7897c5355f net/mlx5: Fix HW spec violation configuring uplink It was added as part of: LP#1926368 "Hirsute update: v5.11.14 upstream stable release" Hence updating the hirsute entry to Fix Released and with that the entire bug. ** Changed in: linux (Ubuntu Hirsute) Status: Fix Committed => Fix Released ** Changed in: ubuntu-z-systems Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1925452 Title: [Ubuntu 21.04] net/mlx5: Fix HW spec violation configuring uplink Status in Ubuntu on IBM z Systems: Fix Released Status in linux package in Ubuntu: Invalid Status in linux source package in Focal: Fix Released Status in linux source package in Groovy: Fix Released Status in linux source package in Hirsute: Fix Released Bug description: SRU Justification: == [Impact] * In addition to 9c9be85f6b59 "net/mlx5e: Add missing capability check for uplink follow" (handled in LP#1921104) another fix 1a73704c82ed "Fix HW spec violation configuring uplink" (handled in this bug, LP#1925452) is needed to fix issues that were introduced with commit 7d0314b11cdd "net/mlx5e: Modify uplink state on interface up/down". * Commit 1a73704c82ed "Fix HW spec violation configuring uplink" fixes a regression for mlx5 adapters required to operate in switchdev mode. * This fix makes sure that the uplink port is modified to follow only if the uplink_follow capability if it's set as required by the hw specification. * Failure cause traffic to the uplink representer net device to cease after switching to switchdev mode.
