Add support for offloading HSR/PRP (IEC 62439-3) tag insertion, tag removal, forwarding and duplication on DSA switches. This series adds offloading to the xrs700x DSA driver. Changes since RFC: * Split hsr and dsa patches. (Florian Fainelli) Changes since v1: * Fixed some typos/wording. (Vladimir Oltean) * eliminate IFF_HSR and use is_hsr_master instead. (Vladimir Oltean) * Make hsr_handle_sup_frame handle skb_std as well (required when offloading) * Don't add hsr tag for HSR v0 supervisory frames. * Fixed tag insertion offloading for PRP.
