Used the ring data structure to implement pool. Also
buffer structure was simplified to enable future driver
interface. Every buffer includes a packet header, so each
buffer can be used as a packet head or segment. Segmentation
was disabled and segment size was fixed to a large number
(64kB) to limit the number of modification in the commit.
