* But for lora where packets can take a few seconds each, it is very important
* to make sure that critical packets are sent ASAP.
* In the case of meshtastic that means we want to send protocol acks as soon as possible
* (to prevent unneeded retransmissions), we want routing messages to be sent next,
* then messages marked as reliable and finally ‘background’ packets like periodic position updates.
*
* So I bit the bullet and implemented a new (internal - not sent over the air)
* field in MeshPacket called ‘priority’.
* And the transmission queue in the router object is now a priority queue.
