Thanks you for reviewing it. Some of the ena_com functions are 
called
with dev* routines because the netdev struct isn't created when 
they
are executed.

We'll go over the other ena com routines (which are called when an
interface exists) and change them to netdev_* routines 
instead. I'll send a new version of the patchset once done.
