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