26 capture each packet, it requires two if you want to get packet's timestamp
35 also has the benefit of minimizing packet copies.
388    - Gap, chosen so that packet data (Start+tp_net) aligns to 
450                         larger than tp_frame_size. This packet can be 
461 TP_STATUS_LOSING      : indicates there were packet drops from last time 
467                         reading the packet we should not try to check the

482 receives a packet it puts in the buffer and updates the status with
483 at least the TP_STATUS_USER flag. Then the user can read the packet,
484 once the packet is read the user must zero the status field, so the kernel 
511 packet, the user fills a data buffer of an available frame, sets tp_len to
570 		2. Read/poll is at a block-level (as opposed to packet-level)
583 In the AF_PACKET fanout mode, packet reception can be load balanced among
584 processes. This also works in combination with mmap(2) on packet sockets.
588   - PACKET_FANOUT_HASH: schedule to socket by skb's packet hash
590   - PACKET_FANOUT_CPU: schedule to socket by CPU packet arrives on
746  *) ~20% increase in packet capture rate
747  *) ~2x increase in packet density
749  *) Non static frame size to capture entire packet payload
751 So it seems to be a good candidate to be used with packet fanout.
999 packet are not buffered, tc disciplines are ignored, increased loss can occur
1012 the packet meta information for mmap(2)ed RX_RING and TX_RINGs.  If your
