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.
George McCollister (4):
net: hsr: generate supervision frame without HSR/PRP tag
net: hsr: add offloading support
net: dsa: add support for offloading HSR
net: dsa: xrs700x: add HSR offloading support
