Added the config-file for ml2_config_sriov in Neutron-server and restart
service . it should work .

Example for SRIOV

/usr/local/bin/neutron-server --config-file /etc/neutron/neutron.conf
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini --config-file
/etc/neutron/plugins/ml2/ml2_conf_sriov.ini & echo $!
>/opt/stack/status/stack/q-svc.pid; fg || echo "q-svc failed to start" |
tee "/opt/stack/status/stack/q-svc.failure"

Title:
  The supported devs value specified in the config  is not taken into
  consideration  w.r.t PCI passthrough

Status in neutron:
  Opinion

Bug description:
  The 'supported_pci_vendor_devs' specified in config is not taken into
  account.

  1.brought up a devstack setup
  2.In the ml2_conf_sriov.ini specified the supported_pci_vendor_devs to 15b3:1007(For mellanox card PF)
  .[ml2_sriov]
  supported_pci_vendor_devs = 15b3:1007
  3.Booted a VM with port having vnic-type=direct-physical

  The port binding fails due to unsupported device vendor type.

  When I manually add 15b3:1007 to 
   cfg.ListOpt('supported_pci_vendor_devs',
                 default=['15b3:1004', '8086:10ca'],

  in
  /opt/stack/neutron/neutron/plugins/ml2/drivers/mech_sriov/mech_driver/mech_driver.py
  the binding succeds.

  the PF vendor product id should be included in the
  supported_pci_vendor type.
