net: add ndo to get id of physical port of the device
This patch adds a ndo for getting physical port of the device. Driver which is aware of being virtual function of some physical port should implement this ndo. This is applicable not only for IOV, but for other solutions (NPAR, multichannel) as well. Basically if there is possible to have multiple netdevs on the single hw port.
