Hi all,

There is a kernel crash bug of ixgbevf kernel module in "Intel(R) 10GbE PCI
Express Virtual Function Driver Version: 4.0.3 Release: 1"

How to produce:
1. Use SRIOV, like this:
sudo /usr/local/share/openvswitch/scripts/dpdk_nic_bind --status

Network devices using DPDK-compatible driver
============================================
0000:01:00.0 'Ethernet Controller 10-Gigabit X540-AT2' drv=igb_uio unused=ixgbe
0000:01:00.1 'Ethernet Controller 10-Gigabit X540-AT2' drv=igb_uio unused=ixgbe

Network devices using kernel driver
===================================
0000:01:10.0 'X540 Ethernet Controller Virtual Function' if=enp1s16 drv=ixgbevf
unused=bak,igb_uio
0000:01:10.1 'X540 Ethernet Controller Virtual Function' if=enp1s16f1
drv=ixgbevf unused=bak,igb_uio
0000:08:00.0 'I350 Gigabit Network Connection' if=eth2 drv=igb unused=igb_uio
0000:08:00.1 'I350 Gigabit Network Connection' if=eth3 drv=igb unused=igb_uio

Other network devices
=====================
<none>

2. bond enp1s16 and enp1s16f1 into bond1, by /etc/sysconfig/ifcfg-bond1.
3. bond 0000:01:00.0 and 0000:01:00.1 in ovs-dpdk into dpdkb2, by dpdk api.
4. stop bond1(ifdown bond1), stop dpdkb2(rte_eth_dev_stop), sleep 5 second,
start dpdkb2(rte_eth_dev_start), start bond1(ifup bond1).

After several times, bug happens, attachment is vmcore-dmesg.txt
