[RFC,net-next,0/3] add HSR offloading support for DSA switches

Message

George McCollister Jan. 22, 2021, 3:59 p.m. UTC

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.

Please let me know if you see any issues or anything that should be
discussed before submitting it as a non-RFC patch series. Since
many may not be familiar with HSR/PRP let me know if I omitted anything
in the commit messages which might have seemed obvious to me.

  net: hsr: generate supervision frame without HSR tag
  net: hsr: add DSA offloading support
  net: dsa: xrs700x: add HSR offloading support
