Subject: [PATCH v3 net 0/6] hsr: HSR send/recv fixes
Date: Wed, 23 Nov 2022 10:56:32 +0100

I started playing with HSR and run into a problem. Tested latest
upstream -rc and noticed more problems. Now it appears to work.
For testing I have a small three node setup with iperf and ping. While
iperf doesn't complain ping reports missing packets and duplicates.

v2…v3:
- dropped patch #7 was an optimisation.

v1…v2:
- Replaced cmpxchg() from patch #6 with lock because RiscV does not provide
  cmpxchg() for 16bit.
- Added patch #3 which fixes the random crashes I observed on latest rc5 while
  testing.
