Agere?

Maybe, a bad label name.
for ex. out_del_napi or whatever.

Documentation/process/coding-style.rst says
"Choose label names which say what the goto does ..."

These three should be merged, for ex.
out_free_device.



I ran sparse for you.

Please take a look if it is worthwhile.
Seems endianess around mac_addr.
