Mac validating package payload
After some Lo Ra chip has demodulated the Lo Ra radio signals for you, it will give you the Lo Ra PHY payload.For a Lo Ra WAN uplink such PHY payload holds a MAC header, MAC payload and MIC.
In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload.
An Ethernet frame is preceded by a preamble and start frame delimiter (SFD), which are both part of the Ethernet packet at the physical layer.
Each Ethernet frame starts with an Ethernet header, which contains destination and source MAC addresses as its first two fields.
In this example we are going to validate if the package org.kodejava.example.xml; import sax.
Mostly programming in Java, Spring Framework, Hibernate / JPA.
