Since there can be many different offloaded operation with many stats types, the ndo gets an attribute id by which it knows which stats are wanted. The ndo also gets a void pointer to be cast according to the attribute id. Signed-off-by: Nogah Frankel Signed-off-by: Jiri Pirko Reviewed-by: Nikolay Aleksandrov Signed-off-by: David S.
