The server tests the 10G network port received sync without timestamp. What is the possible reason..?

Please check Linux Kernel configuration to enable DPAA SDK Ethernet driver and HW timestamping support

Device Drivers --->
[*] Network device support --->
    [*] Ethernet driver support --->
       [*] Freescale devices
       <*> DPAA Ethernet --->

What is the relationship between "ptp-qoriq" and "FM RTC timer"  。。？

Freescale QorIQ 1588 timer as PTP clock
modulename: ptp-qoriq.ko

I have selected the above configuration:
