Date: Fri, 27 Dec 2019 15:02:27 +0200 From: Vladimir Oltean <olteanv@...il.com> To: davem@...emloft.net, jakub.kicinski@...ronome.com Cc: richardcochran@...il.com, f.fainelli@...il.com, vivien.didelot@...il.com, andrew@...n.ch, netdev@...r.kernel.org, Vladimir Oltean <olteanv@...il.com> Subject: [PATCH v2 net-next 0/3] Improvements to SJA1105 DSA RX timestamping This series makes the sja1105 DSA driver use a dedicated kernel thread for RX timestamping, a process which is time-sensitive and otherwise a bit fragile. This allows users to customize their system (probabil an embedded PTP switch) fully and allocate the CPU bandwidth for the driver to expedite the RX timestamps as quickly as possible. While doing this conversion, add a function to the PTP core for cancelling this kernel thread (function which I found rather strange to be missing).
