Each rtnet device registered with the stack is represented by a node into /sys/devices/virtual/rtnet/. Setting the address of the real device probed by the kernel into the rtnet_device.sysbind field before calling rt_register_rtnetdev(), causes the "adapter" symlink to be installed in the newly created attribute directory, pointing at that device. e.g. static int probe_handler(struct pci_dev *pdev, const struct pci_device_id *ent) { ... rtdev->sysbind = &pdev->dev; ... ret = rt_register_rtnetdev(rtdev); ... } $ ls -l /sys/devices/virtual/rtnet/ total 0 drwxr-xr-x 2 root root 0 Mar 30 12:50 enp1s0 drwxr-xr-x 2 root root 0 Mar 30 12:50 rtlo $ ls -l /sys/devices/virtual/rtnet/enp1s0/ total 0 lrwxrwxrwx 1 root root 0 Mar 30 12:51 adapter -> ../../../pci0000:00/0000:00:13.0/0000:01:00.0 lrwxrwxrwx 1 root root 0 Mar 30 12:51 subsystem -> ../../../../class/rtnet -rw-r--r-- 1 root root 4096 Mar 30 12:50 uevent
