@regaeCould you please create a pull request with this change. Please create it as a separate patch. It would be nice if you could also send this to the upstream Linux kernel. Do you or anyone else have access to the schematics of this device or the none LTS version? If you have ac...
CONFIG_NET_DSA_SJA1105_PTP: enables additional support for the PTP Hardware Clock (PHC), visible in /dev/ptp1 on the LS1021A-TSN board, and for PTP timestamping on the SJA1105 ports CONFIG_NET_DSA_SJA1105_TAS: enables additional support for the Time-Aware Scheduler (TAS), which is...
This post shows how to steer PTP traffic to single RX ring via ethtool commands. PTP traffic uses UDP ports 320 and 319, As a result of RSS (Receive Side Steering) PTP traffic coming to UDP ports 319 and 320, it may arrive to the user space application out of order. In order to ...
