I chose to keep the new helper which also looks at the chain but renamed it more appropriately. The rationale being that most drivers don't accept chains other than 0 and since we have to pass extack to the helper we can as well pass the entire struct tc_cls_common_offload and perform the most common checks. This code makes the assumption that type_data in the callback can be interpreted as struct tc_cls_common_offload, i.e. the real offload structure has common part as the first member. This allows us to make the check once for all classifier types if driver supports more than one. v1: - drop the type validation in nfp and netdevsim. v2: - reorder checks in patch 1; - split other changes from patch 1; - add the i40e patch in; - add one more test case - for chain 0 extack. ==================== Signed-off-by: David S.
