The idea behind this is to allow incoming packets to be sorted into different pools based on their lengths for storage efficiency. For example, you might have three pools of sizes 256 bytes, 1500 bytes, and 9200 bytes and sort arriving packets into them based on their lengths. So each arriving packet winds up being stored as a single segment in an appropriately-sized pool.
