At least with (only) this patch applied, rnpgbe_driver_name
appears to only be used in this file. So it should be static.

Flagged by Sparse.

Please make sure that when each patch in the series is applied in turn,
no new Sparse warnings are introduced. Likewise for build errors.
And ideally warnings for W=1 builds.
