Hi, To correlate between PCI device and net device in linux you can inspect sysfs: # ls -l /sys/bus/pci/devices/<PCI_DEVICE_ADDRESS>/net To correlate between net device and PCI device: # ls -l /sys/class/net/<NET_DEVICE>/device a Virtual PCI function (VF) will have a pointer to its Physical function (PF) /sys/bus/pci/devices/<PCI_DEVICE_ADDRESS/physfn If the file doesn't exist you can assume it's a PF. Thanks, Adrian.
