Target Milestone --- 

af_packet use packet fanout, set f=
lag: PACKET_FANOUT_FLAG_DEFRAG, if set,
causes packets to be defragmented before fanout is applied, the packets that
read from AF_PACKET socket maybe larger than the frame size and the mbuf si=
ze,
so the packet will be truncated.

In PACKET_FANOUT mode, each matching packet is enqueued onto only one socke=
t in
the group. But when af_packet use one rx queue, there is no need to set pac=
ket
fanout.
