The introduced patches add possibility of using PTP in different VLANs on a single L2 interface. The core change is a new transport - RAW UDPv4 that uses RAW sockets and BPF filter to process PTP packets for a given VLAN. With this transport PTP can be configured on the interfaces without an IP address, but port configuration section should specify special L3 interface (VLAN interface), address of which is used as a source address for the outgoing packets. Thus these patches add support of PTP on VLAN interfaces.
