Ubuntu 16.10 KVM SRIOV: if enable sriov while ping flood is running
ping will stop working

Bug description:
---Problem Description---
If I enable SRIOV in a Mellanox CX4 card while a PF interface is doing something like a ping flood. The PF interface will stop pinging.
We found a small window were MMIO are bein g disabled during pci_enable_sriov is called.
---uname output---
4.4.0-30-generic
---Additional Hardware Info---
It needs a Mellanox CX4 SRIOV capable to recreate this issue
Machine Type = P8
---Steps to Reproduce---
just configure the IP address of PF interface and start like a ping flood to that interface.
then do this echo to enable SRIOV on the PF.
echo 8 > /sys/class/net/enP1p1s0f0/device/sriov_numvfs
Then you will notice the ping flood will stop.
