Missing Unique GatewayEUI check on LinkCheckAns

[ghost]

What happened?

When a gateway receives a frame with a very strong signal it can be received on both RF Frontends in the gateway. This will make the gateway receive the same frame two times.
As the gateway is a simple forwarder of frames no duplicate detection is done here.

When this duplicate frame contains a LinkCheckReq the network server will count the GW count up for both duplicate packets even though they originate from the same gateway.

What did you expect?

As i understand it the gateway count in LinkCheck MAC command should count unique gateways based on the GatewayEUI.

Steps to reproduce this issue

Transmit a LinkCheckReq on a channel that is close to both RF Frontend filter boundaries.
The frame could be received two times on the gateway, once for each RF Frontend.
The Network server will reply with 2 GW Count in the LinkCheckAns.

Could you share your log output?

The orange field is the GatewayEUI where it can be seen that the duplicate LinkCheckReq is received 2x.
The blue is the DeviceEUI where the GWCount = 2 is transmitted to in the LinkCheckAns.

Your Environment

The network server is version 3.10.0
