Use the `__struct_group()` helper to create a new tagged `struct ethtool_link_settings_hdr`. This structure groups together all the members of the flexible `struct ethtool_link_settings` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. This new tagged struct will be used to fix problematic declarations of middle-flex-arrays in composite structs[1]. [1] https://git.kernel.org/linus/d88cabfd9abc Signed-off-by: Gustavo A. R.
