Hi Experts,

Linuxptp seems to be not supported in vnic and bond interface and throws the 
following error:
root@ptp-slave:~# ptp4l -i vnic2 -A -4 -m
ptp4l[670.880]: interface 'vnic2' does not support requested timestamping mode
failed to create a clock

Kindly let me know if there is a way for supporting ptp over bond/vnic 
interfaces

vnic2 is created on interface enp1s0f1.
