IOW, you are using your own unpublished custom driver.  Sorry, can't
help you with that.

If there is an issue with TLV handling, please reproduce it using
standard drivers and unaltered linuxptp sources.  Then, post the
details of the configuration.

I hope so.

Thanks,

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).

Exactly. Connection is established using the BroadR-Reach <-> Ethernet
converter, if it matters.

SOF_TIMESTAMPING_TX_SOFTWARE,

Is it crucial? Am I able to add support of this timestamp mode by myself?

You mean endianess of *ptr variable value? Because if I have for example
0x68e3 or 0xe368 values for tlv->length field, it doesn't change much.
I have a raw value of *ptr equal to 0x68e3, doesn't it seem like a
correct value? It implies that tlv->type equals 0.

Thanks.
