 ptp4l -i eth0 -m -A (The -A enables automatic selection of the delay

sorry for my mistake I have copied and pasted same message three times.
following are real time message

ptp4l[2460.587]: port 1: received PDELAY_REQ without timestamp
ptp4l[2461.589]: port 1: received PDELAY_REQ without timestamp
ptp4l[2462.590]: port 1: received PDELAY_REQ without timestamp
ptp4l[2463.590]: port 1: received PDELAY_REQ without timestamp
ptp4l[2464.592]: port 1: received PDELAY_REQ without timestamp
ptp4l[2465.594]: port 1: received PDELAY_REQ without timestamp
ptp4l[2466.594]: port 1: received PDELAY_REQ without timestamp

once I exit from application
[ 2506.471859] cpts: unable to obtain a time stamp
[ 2514.487888] cpts: event pool is empty
