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. Changes since v2: * Return -EOPNOTSUPP instead of 0 in dsa_switch_hsr_join and dsa_switch_hsr_leave. (Vladimir Oltean) * Only allow ports 1 and 2 to be HSR/PRP redundant ports. (Tobias Waldekranz) * Set and remove HSR features for both redundant ports. (Vladimir Oltean) * Change port_hsr_leave() to return int instead of void. * Remove hsr_init_skb() proto argument.
