Question: Adding Data to SYN Packet

[KYTG-Dev]

Describe the bug / error

I am trying to find a solution to implement a flow similar to what is achieved in TCP Fast Open where we send data along with a SYN packet. If we have two Envoy hosts which want to talk to each other, each with a TinyGo WASM filter, how can we add data to the SYN packet on the sending side and inspect it on the receiving side?

What is your Envoy/Istio version?

Envoy version 1.28.0

What is the SDK version?

v0.23.0

What is your TinyGo version?

v0.30.0

URL or snippet of your code including Envoy configuration
