Complete example code showing how to construct a UDP packet from scratch and inject it on a WiFi interface in Linux
/**
* Hello, and welcome to this brief, but hopefully complete, example file for
* wireless packet injection using pcap.
*
* Although there are various resources for this spread on the web, it is hard
* to find a single, cohesive piece that shows how everything fits together.
* This file aims to give such an example, constructing a fully valid UDP packet
* all the way from the 802.11 PHY header (through radiotap) to the data part of
* the packet and then injecting it on a wireless interface
