Hello,
I have seen that post in sourceforge:
https://sourceforge.net/p/linuxptp/mailman/message/35474590/
It is suggested there:
You need to add one line to the transmit path in the driver:
skb_tx_timestamp(skb);
Quoting include/linux/skbuff.h:
* skb_tx_timestamp() - Driver hook for transmit timestamping
*
* Ethernet MAC Drivers should call this function in their hard_xmit()
* function immediately before giving the sk_buff to the MAC hardware.
*
* Specifically, one should make absolutely sure that this function is
* called before TX completion of this packet can trigger. Otherwise
* the packet could potentially already be freed.
I have the same issue currently, but I could not resolve it. Where is
the timestamp
path in the driver? I tried to add that code piece to driver
installation files which
didn't work.
Test Environment: zcu102 & XG-C100F ethernet card.
