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.
