  Target Milestone: ---

I am validating DPDK receive functionality & for this I'm shooting a pcap
externally & added code in l2fwd to dump received packets to pcap, the l2fwd
dumped pcap have all the packets from shooter but some of them are not in
sequence. Shooter is already validated.
Out of order packets are random. For the first run I saw 3 out of order packets
and on the second run there were 6 packets out of order.

NIC used : Mellanox Connectx-6Dx l2fwd arguments : dpdk-l2fwd.exe -l 1,2 -n 1
-- -p 0x3 -q 1 -P.
