Does isochron work on LS1028 switch port? #22

Hi, @vladimiroltean The NXP ls1028 board has two TSN ports, one is ENETC and others are DSA felix_vsc9959. The isochron works on the ENECT port but it seems not working on the DSA ports. So, I wonder if the isochron works on LS1028 switch port? I found out that the SOF_TIMESTAMPING_TX_HARDWARE can not achived by setting setsockopt(fd, SOL_SOCKET, SO_TIMESTAMPING, &flags, sizeof(flags)). Thanks

No, you cannot make the switch ports on LS1028A timestamp non-PTP packets, which isochron requires.
