Detailed Description

Structure prepended to each packet in the kernel buffer pool.

Each packet in one of the kernel buffers is prepended by this header. It encapsulates the bpf_header, which will be passed to user level programs, as well as the sequence number of the packet, set by the producer (the tap function), and used by the consumer (the read function) to "reorder" the packets contained in the various kernel buffers.
