This makes it possible to use a range of JoinEUIs per Join Server.
Use-cases are either Join Servers using a JoinEUI range or the
configuration of a "catch-all" Join Server prefix ("0000000000000000/0").
Historically, the tx power was defined as ERP. The Semtech UDP Packet
Forwarder protocol was never explicit if the "powe" field was in ERP or
EIRP. However, as the antenna gain in the Semtech UDP Packet Forwarder
is documented as dBi and is deducted from the "powe" field, this means
that "powe" is in EIRP.
This commit corrects all values to EIRP, to make sure that if the
antenna gain is properly configured (which should be), that the correct
rf_power is used by the gateway.
The frequency-hopping ping-slots are equal to the beacon frequencys.
With the US915 and AU915 channels using the Class-A downlink
channels as beacon-frequencies, this was wrongly implemented in the
same way, but in case of CN470 the beacon-frequencies are not equal
to the Class-A downlink frequencies.
Per Regional Parameters Specification, the LoRa modulation always uses
coding-rate 4/5, however this is not the case for ISM2400 (which is
currently not covered by the reg. params) in which case coding-rate
4/8LI must be used.
Closes#51.
This type defines the (NetID derived) prefix that must be used when
generating device addresses. This can be retrieved from the NetID, but
it is also possible to define a prefix that defines a smaller address
range within the NetID.
