+               Network packet headers contain a great deal of information, but the kernel often only needs a subset of that information to be able to perform filtering or associate any given packet with a flow. The piece of code that follows the different layers of packet encapsulation to find the important data is called a flow dissector. In current Linux kernels, the flow dissector is written in C. A patch set has been proposed recently to implement it in BPF with the clear goal of improving security, flexibility, and maybe even performance.
