Merge branch 'dsa-hsr-offload'
George McCollister says:
====================
add HSR offloading support for DSA switches
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)
