Jakub Kicinski says: ==================== use tc_cls_can_offload_and_chain0() throughout the drivers This set makes all drivers use a new tc_cls_can_offload_and_chain0() helper which will set extack in case TC hw offload flag is disabled. 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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
