Within the ChirpStack Gateway Mesh configuration we are using uplink frequencies for Relay <> Relay and Relay <> Border gateway communication. However, the min / max tx frequencies that the Concentratord enforces are only for LoRaWAN downlinks. For EU868 this is not an issue because the channels are equal, but it prevents Relay and Border gateways from transmitting using uplink frequencies (such that the other gateway is able to receive it).
I think we should make the min / max freqs an vector, such that different frequency blocks can be configured, e.g.
[[a, b], [c, d]]
I such case, there could be a frequency gap between b - c on which the gateway does not allow transmitting downlinks.
