27  * Multi producer, single consumer packet buffer allows to allocate variable
28  * length consecutive space for storing a packet. When space is allocated
29  * it can be filled by the user (except for the first 2 bits) and when packet
30  * is ready it is committed. It is allowed to allocate another packet before
33  * If buffer is full and packet cannot be allocated then null is returned unless
37  * packet is dropped and claimed packet is marked as invalid when freeing.
39  * Reading packets is performed in two steps. First packet is claimed. Claiming
40  * returns pointer to the packet within the buffer. Packet is freed when no
