I know it is problematic because we try to assign the same name
to both network devices, if we assign a name to the primary
network device.  That can't work.

Beyond that I had some really weird crashes while testing this
piece of code, especially when I did not specify a peer parameter.

So it was just easier to avoid the problem with this patch then
to completely root cause it.

I think the easiest semantic is to not have any peer parameters
if they were not specified, then to try and to figure out which
subset of parameters to copy.  If I hadn't been getting weird
kernel crashes I would not have cared.
