Is it the WRS that needs to be updated? their web page says "Technically, the White Rabbit Network is a Bridged Local Area Network with VLANs (IEEE 802.1Q) that uses Ethernet (IEEE 802.3) to interconnect switches and nodes, and the Precision Time Protocol (PTP, IEEE 1588-2008) to synchronise them." and I understand that 1588-2008 is 2.0 whie 1588-2019 is 2.1, isn't it? so I am not clear if WRS is broadcasting PTP v2.1 packets. Is there a rationale for preventing out of the box linuxptp from working with both PTP 2.0 and 2.1 packets, since changing the constant in the header file seems to make the protocol operational again?
