What percentage of the packet, just roughly, is taken by the header and tail?

@Holladay, it depends. A packet could be a 64 byte cache line, or an 8 byte address, or .... The size of the head and tail depends on implementation, but the couple that I surveyed use about 2-4 bytes each for the header and tail.
