This is a note to let you know that I've just added the patch titled net/mlx5e: Fix macsec ASO context alignment to the 6.2-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-mlx5e-fix-macsec-aso-context-alignment.patch and it can be found in the queue-6.2 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5f3ca326a8bd173fc3f0640efb86c59beb33d76d Author: Emeel Hakim <ehakim@xxxxxxxxxx> Date: Wed Feb 8 14:25:54 2023 +0200 net/mlx5e: Fix macsec ASO context alignment [ Upstream commit 37beabe9a891b92174cd1aafbfa881fe9e05aa87 ] Currently mlx5e_macsec_umr struct does not satisfy hardware memory alignment requirement. Hence the result of querying advanced steering operation (ASO) is not copied to the memory region as expected. Fix by satisfying hardware memory alignment requirement and move context to be first field in struct for better readability.
