In order to support the multipeer architecture, upon connection setup each side of a tunnel advertises a unique ID that the other side must include in packets sent to them. Therefore when transmitting a packet, a peer inserts the recipient's advertised ID for that specific tunnel into the peer ID field. When receiving a packet, a peer expects to find its own unique receive ID for that specific tunnel in the peer ID field. Add support for the TX peer ID and embed it into transmitting packets. If no TX peer ID is specified, fallback to using the same peer ID both for RX and TX in order to be compatible with the non-multipeer compliant peers.
