    IBM PowerKVM: Configuring SR-IOV VFs on Different ConnectX-3 Ports

      Hi

       

       

       

      IBMPowerKVM server, which has a  Connectx-3 Pro card [FW: 2.33.5106] , I tried loading mlx4_core as below:

       

      modprobe mlx4_core port_type_array=2,2 num_vfs=8,0,0 probe_vf=8,0,0  log_num_mgm_entry_size=-1

       

      Which should ideally have created 8 VFs probed on 1st port. But I am seeing below under ip link o/p:

       

      ip link show enP5p1s0

      62: enP5p1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT qlen 1000

          link/ether f4:52:14:3b:22:10 brd ff:ff:ff:ff:ff:ff

          vf 0 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 1 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 2 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 3 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 4 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 5 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 6 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 7 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

      ip link show enP5p1s0d1

      63: enP5p1s0d1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT qlen 1000

          link/ether f4:52:14:3b:22:11 brd ff:ff:ff:ff:ff:ff

          vf 0 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 1 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 2 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 3 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 4 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 5 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 6 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

          vf 7 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto

       

      Where enP5p1s0d1 and enP5p1s0 are the interface names of dual port mellanox connectx-3 Pro.

      I have read instructions @ HowTo Configure SR-IOV VFs on Different ConnectX-3 Ports

      I am seeing VF for both ports and none of them seems to be dummy.. as I understand from HowTo Configure SR-IOV VFs on Different ConnectX-3 Ports  , dummy vf ports will be assigned with MAC and vlan to 0xff(s).

       

      I could open a bug from official channel if you think its a genuine issue.
