i want to config mellanox infiniband mode sr-iov with openstack liberty by use neutron as link ：SR-IOV-Passthrough-For-Networking - OpenStack
in compute host have two mellanox infiniband card，i confige them SR-IOV with neutron，and install neutron sriov nic agent， but when i complete this configuration，restart this neutron sriov nic agent，it has error as ：
WARNING neutron.plugins.ml2.drivers.mech_sriov.agent.pci_lib [-] Cannot find vfs [0, 1, 2, 3, 4, 5, 6, 7] in device ib0，but i use lspci command which can see the vfs：
lspci | grep -i mella

21:00.2 Network controller: Mellanox Technologies MT27500/MT27520 Family [ConnectX-3/ConnectX-3 Pro Virtual Function]
when i set options mlx4_core num_vfs=8 port_type_array=2,2 probe_vf=0 enable_64b_cqe_eqe=0 log_num_mgm_entry_size=-1，i will see ip link show like this：
eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT qlen 1000
link/ether 24:be:05:ab:14:f2 brd ff:ff:ff:ff:ff:ff

vf 7 MAC ff:ff:ff:ff:ff:ff, vlan 65535, spoof checking off, link-state auto
but my switch just support infiniband mode，so this link is down and NO-CARRIER。
when i set options mlx4_core num_vfs=8 port_type_array=1,1 probe_vf=0 enable_64b_cqe_eqe=0 log_num_mgm_entry_size=-1，i will see ip link show like this：
ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovs-system state UP mode DEFAULT qlen 1000
but no vf can be seen。
who has any idea ？thanks
