What I am seeing now, after inserting skb_tx_timestamp(skb)  as I
explained before :

Master side :
root@master:/linux-ptp# ./ptp4l -S -i wlan0 -m
ptp4l[1591.227]: port 1: get_ts_info not supported
ptp4l[1591.237]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[1591.237]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[1597.237]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES

This seems OK.

But on the slave side :
root@slave:/linux-ptp# ./ptp4l -S -i wlan0 -s -m
ptp4l[228.367]: port 1: get_ts_info not supported
ptp4l[228.371]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[228.372]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[229.013]: port 1: new foreign master deadbe.fffe.ef0000-1
ptp4l[232.902]: selected best master clock deadbe.fffe.ef0000
ptp4l[232.902]: foreign master not using PTP timescale
ptp4l[232.902]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE
ptp4l[234.056]: poll tx timestamp failed: No such file or directory
ptp4l[234.056]: port 1: send delay request failed
ptp4l[234.056]: port 1: UNCALIBRATED to FAULTY on FAULT_DETECTED
(FT_UNSPECIFIED)
ptp4l[250.060]: port 1: FAULTY to LISTENING on FAULT_CLEARED
ptp4l[250.923]: port 1: new foreign master deadbe.fffe.ef0000-1
ptp4l[255.019]: selected best master clock deadbe.fffe.ef0000
ptp4l[255.019]: foreign master not using PTP timescale
ptp4l[255.019]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE
ptp4l[255.443]: poll tx timestamp failed: No such file or directory
ptp4l[255.443]: port 1: send delay request failed
ptp4l[255.444]: port 1: UNCALIBRATED to FAULTY on FAULT_DETECTED
(FT_UNSPECIFIED)




What is :
ptp4l[234.056]: poll tx timestamp failed: No such file or directory
ptp4l[234.056]: port 1: send delay request failed


and how is it different than :
ptp4l[106753.952]: poll tx timestamp failed: Success
ptp4l[106753.952]: port 1: send sync failed
ptp4l[106753.952]: port 1: MASTER to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED)

that I was seeing on MASTER side before skb_tx_timestamp(skb) was
inserted in the driver ?

Best regards,
Drasko
