Even in kernel version 4.15.2 in file net/8021q/vlan_dev.c function vlan_ethtool_get_ts_info contains the following code: info->so_timestamping = SOF_TIMESTAMPING_RX_SOFTWARE | SOF_TIMESTAMPING_SOFTWARE; And it seems that absence of SOF_TIMESTAMPING_TX_SOFTWARE flag in this place is leading to fail in ethtool check. Is adding the flag in this function is all I need to do to implement this functionality? It seems like it isn't, but I'm not sure. Don't you know any manual I could refer? Also, as a network driver I am using a custom EoP driver. Do you have any ideas about on which stage something can go wrong? I guess that the problem may be caused by this driver.

Re: [Linuxptp-users] Bad message error
I also checked the values for the working case, where the host behaves as a slave, and I found out that: 1) *ptr value is always set to 0x; 2) len (cnt - pdulen) is either 0 or 2, i.e. it is always less then sizeof(struct TLV).
