We are working towards the Avnu conformance tests for 802.1AS-2020, and actually Avnu do validate whether the device can properly ignore unknown TLVs in received PTP messages. Without this implementation, we observe "bad message" error when the device receives Sync, Pdelay_Req and Pdelay_Resp event messages with unknown TLV appended.
