Hi all,

we are evaluating ptp4l master with hardware timestamp in E810-XXVDA4TGG1 and timed out while polling for tx timestamp is frequently occurring  as below

so ptp4l slave will easy lose sync as below

The ptp4l used above is ok for other intel NIC adaptor and there is no error of timed out while polling for tx timestamp.   We are not sure what reason for this problem. pls give some advise. Thanks in advance!

 

Btw

(1)ptp4l master command is like below

ptp4l -i enp23s0f3 -p /dev/ptp3 -H -2 -m -l 6

or

ptp4l -i enp23s0f3 -H -2 -m -l 6

 

(2)firmware version of E810-XXVDA4TGG1 is below

firmware-version: 3.10 0x8000d29a 1.3106.0
