Message

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.

Resent. Jakub says "looks like this is not showing up in patchwork
probably because of the ML server issue - please repost"

Changes since RFC:
 * Split hsr and dsa patches. (Florian Fainelli)

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