Detailed Description

Structure used to store data gathered by the taps and dissector that is attached to the pinfo structure for the packet. This structure ends up getting allocated for every packet. So, we want to keep it small.

For fields that are 1 bit wide, they have 0 == false and 1 == true. For fields that are 2 bits wide, they have 0 == false, 1 == true and 3 == unknown.
