Referencing the default settings, the Gateway transmits up to 213 bytes on every hop. If fewer than 213 bytes
are transmitted by the Gateway, the balance is allocated to the Endpoint's transmission, plus the quantity in
the Min Packet Size setting. For example, if a Gateway transmits 100 bytes, the Endpoint then has a total of
134 bytes available [113 (“leftover bytes”) + 21 (Min packet size)].
