> The master device and VF representors were distinguished by presence of
> port name, master device did not have one. The new Linux kernels starting
> from 5.0 provide the port name for master device and the implemented
> representor recognizing method does not work.
> The new recognizing method is based on querying the VF number, has been
> created on the base of the device.
>
> The IFLA_NUM_VF attribute is returned by kernel if IFLA_EXT_MASK
> attribute is specified in the Netlink request message.
>
> Also the presence check of device symlink in device sysfs folder is added to
> distinguish representors with sysfs based method.
