Hello, I'm currently a PTPd user but I'm interested in ptp4l especially if I can take advantage of hardware timestamp support. First step was to see if I could simply run ptp4l utilizing software timestamps and I ran into a bit of a snag. We currently run ptpd on a vlan but attempting 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 underlying device interface eth4 however does claim to support SOF_TIMESTAMPING_TX_SOFTWARE. So I guess I have a couple of questions here regarding ptp4l and vlans. The first big question is of course is it possible to run ptp4l on a vlan? Assuming the actual device and driver support hardware timestamps (or software TX) and provide a PHC is it possible to access those through a vlan?
