DescriptionIn the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Use correct encap attribute during invalidation With introduction of post action infrastructure most of the users of encap attribute had been modified in order to obtain the correct attribute by calling mlx5e_tc_get_encap_attr() helper instead of assuming encap action is always on default attribute. However, the cited commit didn't modify mlx5e_invalidate_encap() which prevents it from destroying correct modify header action which leads to a warning [0]. Fix the issue by using correct attribute.
