This is a note to let you know that I've just added the patch titled net/mlx5: SF, Stop waiting for FW as teardown was called to the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-mlx5-sf-stop-waiting-for-fw-as-teardown-was-call.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 0eae8e93240ef66feae0a0b934a068cc38bbd3a9 Author: Moshe Shemesh <moshe@xxxxxxxxxx> Date: Thu Jan 25 14:24:09 2024 +0200 net/mlx5: SF, Stop waiting for FW as teardown was called [ Upstream commit 137cef6d55564fb687d12fbc5f85be43ff7b53a7 ] When PF/VF teardown is called the driver sets the flag MLX5_BREAK_FW_WAIT to stop waiting for FW loading and initializing. Same should be applied to SF driver teardown to cut waiting time. On mlx5_sf_dev_remove() set the flag before draining health WQ as recovery flow may also wait for FW reloading while it is not relevant anymore.
