This has the not so nice side effect that in case of dev_open() error,
the device will flip status after dpaa2_eth_setup_xdp(). We should try
to avoid that.

I think it's better if you export the helper instead (or even better,
do something more low level-cant-fail like stop the relevant h/w queue,
reconfigure, restart the h/w queue).

Cheers,
