This is easily fixed using either udev or the ifrename tool.  Either of
those will let you associate arbitrary names with your nics, keyed to
the mac address.  For example, we have some key routers at work with 8
network ports bonded into 4 pairs and I didn't want that being messed
up, so I used udev to rename the nics to ether0, ether1 etc and gave the
bonded interfaces names that reflected their purpose.

You can give interfaces any name you want but I went with etherN for the
physical cards because there are some braindead userspace tools whose
idea of checking that the interface represents an ethernet device by
(I kid you not) checking the first three letters of the name.
