How To get Linkcheck Data from PORT0

[Keo]

We can TX a MAC linkcheck request on PORT0 but we can't receive anything on that PORT. It would be nice if lora_stats() include the linkcheck answer (Link margin and Number of Gateways). We can listen on other PORTs. Unfortunately, the server sends back the MAC link check answer only on PORT0.
