The problem in this case is that they have this huge suite of
functions that operate on a specific ena sub-object.  Most of the time
the associated netdev is fully realized, but in the few calls made
during early probe it is not.

To me it is a serious loss that just because a small number of times
the interface lacks a fully realized netdev object, we can't use the
netdev_*() routines.

Most users aren't going to understand that an error message for PCI
device XyZ means eth0 is having problems.
