ring: netsniff-ng: migrate capture only to TPACKET_V3
Lets migrate capturing to TPACKET_V3, since it will bring a better
performance due to fewer page cache misses caused by a higher density
of packets, since now they are contigous placed in the ring buffer.
It is said that TPACKET_V3 brings the following benefits:
*) ~15 - 20% reduction in CPU-usage
*) ~20% increase in packet capture rate
*) ~2x increase in packet density
*) Port aggregation analysis
*) Non static frame size to capture entire packet payload
