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. (Vladimir Oltean)
