Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com>, Thomas Gleixner <tglx@...utronix.de>, Kurt Kanzenbach <kurt@...utronix.de> Subject: [PATCH v4 net-next 0/8]: hsr: HSR send/recv fixes 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. v3…v4: - Targeting net-next now. - Added patch #7 back to basket. Kurt's review comments are addressed. - Added a basic test for HSRv0. 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.
