Bug 470

Environment:

Vmware ESXi 6.5.0


vmxnet3 bind information:

Network devices using DPDK-compatible driver
============================================
0000:03:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=uio_pci_generic
0000:0b:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=uio_pci_generic


I changed vmxnet3_recv_pkts function to use rte_pktmbuf_dump dump all the mbuf pakcet received。

I changed vmxnet3_recv_pkts like this:

+ int i;

........

 rcd_done:
+			for (i = 0; i < nb_rx; i++) {
+				struct rte_mbuf *m = rx_pkts[i];
+				rte_pktmbuf_dump(stdout, m, m->pkt_len);
+			}

Then I run our program and redirect the dump information to a file. Same time, I used ping6 to send icmp6 ns packet in another virtual machine。
 
After awhile I greped icmp6 ns packet type from dumped file，but got none packet dump information.

After that, I binded vmxnet3 to kernel driver, and setted ipv6 address，this time the interface can received icmp6 ns packet.
