[Linuxptp-users] recvmsg tx timestamp failed: Resource temporarily unavailable

[Rayagond K. <ray...@gm...>]

Hi All

I am getting following messages when I run the command - ptp4l -i eth1
-p /dev/ptp0 -m

ptp4l[9393.328]: selected /dev/ptp0 as PTP clock
ptp4l[9393.330]: failed to read out the clock frequency adjustment:

ptp4l[9437.363]: port 1: FAULTY to LISTENING on FAULT_CLEARED

What does this error means ?

I am returning the timestamp back to socket using "skb_tstamp_tx()"
api in my driver.
