WebThe linuxptp package includes the ptp4l and phc2sys programs for clock synchronization. The ptp4l program implements the PTP boundary clock and ordinary clock. With hardware time stamping, it is used to synchronize the PTP hardware clock to the master clock, and with software time stamping it synchronizes the system clock to the master clock. Webattempting to run ptp4l on a vlan interface results in the following: # ptp4l -S -i vlan807 -s -l7 -m interface 'vlan807' does not support requested timestamping mode. I took a look at the code and can see this is because vlan interfaces do not report that they support SOF_TIMESTAMPING_TX_SOFTWARE. The
