Subject: [PATCH net-next v2 0/4] 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.

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
