Subject: [PATCH] net: rocker: Change netdev names to include slot number

Currently, rocker devices are given eth%d names. If you have multiple
rocker devices it is difficult to easily correlate eth%d names to a
rocker device and port. Change the device name to sw + PCI slot
number + p + id (sw%dp%d). This makes the device names easier to
correlate. ie., Rather than eth0, ..., eth N (N = number of ports in
device) the ports get netdev names like sw5p0, ..., sw5pN.
