What is the intention of the 'user' field in:
public void nextPacket(PcapPacket packet, T user);
Thanks in advance for your help. Great product.
Lets you pass in any type of object that is helpful to your handler. A good usage for it is to pass some kind of 'state' object. So if you use the same handler with multiple PCAP interfaces, each one can keep different state and you do not have to perform any kind of lookup (per interface) to get at a state object.
