Commit Message

Vladimir Oltean Dec. 21, 2023, 1:25 p.m. UTC 
For testing the tc-taprio software scheduling path, we don't need PTP
synchronization at all, but isochron_do() was written assuming that we
do.

Allow skipping the UNIX domain socket for the ptp4l instance on the
sender, and pass --omit-sync to isochron instead, so that it sends right
away and does not monitor the PTP quality.
