Public bug reported:

escription of problem:
When manage SR-IOV PFs as Neutron ports I can see that 
/sys/class/net/enp5s0f1/device/sriov_numvfs parameter gets "0" value . 
when I delete the PF port  so I can switch to SRIOV - direct port (VF) I cant boot vm because sriov_numvfs parameter equal to "0" value

How reproducible:
always 

Steps to Reproduce:
1.Set SRIOV ENV and PF support : https://docs.google.com/document/d/1qQbJlLI1hSlE4uwKpmVd0BoGSDBd8Z0lTzx5itQ6WL0/edit#
2. BOOT VM that assign to PF (neutron port- direct-physical) -  should boot well
3. check cat /sys/class/net/enp5s0f1/device/sriov_numvfs  (=0)
4. delete vm  and check again sriov_numvfs   (=0)
5. I expect that numvfs should return to the default value that was configured
