[Linuxptp-users] Issues with linuxptp and Intel 82574

[Fabrizio G. <Fab...@ri...>]

Hello everyone,

I've been trying to use linux with my Intel 82574 with no much luck.
First I've tried to use it with software timestamping since the version of e1000e I was using didn't support HW timestamping.
This is what I get:

[root@199-dorothy13 ~]# ptp4l -i eth0 -v -S
ptp4l[25333.043]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[25333.043]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[25334.561]: port 1: new foreign master 003048.fffe.9ea9d6-1
ptp4l[25338.561]: selected best master clock 003048.fffe.9ea9d6
ptp4l[25338.561]: port 1: LISTENING to GRAND_MASTER on RS_GRAND_MASTER
ptp4l[25339.567]: recvmsg tx timestamp failed: Resource temporarily unavailable
ptp4l[25339.567]: port 1: send sync failed
ptp4l[25339.567]: port 1: GRAND_MASTER to FAULTY on FAULT_DETECTED
ptp4l[25354.574]: port 1: FAULTY to LISTENING on FAULT_CLEARED

What is that supposed to mean? Resource temporarily unavailable?

So I decided to update my e1000e driver to the latest version available (2.5.4) and use HW timestamping.
After rebooting my machine I try to run it with HW support (no option -S) and this is what I get:

ptp4l[25432.718]: driver rejected most general HWTSTAMP filter
ptp4l[25432.718]: ioctl SIOCSHWTSTAMP failed: Numerical result out of range
ptp4l[25432.722]: port 1: INITIALIZING to FAULTY on INITIALIZE
ptp4l[25432.722]: port 0: INITIALIZING to LISTENING on INITIALIZE

Does anyone know what's going on?
Thank you very much!
