Oh. Whoops. That's what I get for only testing without CONFIG_PCPU_DEV_REFCNT... I guess a better place to put the new check would be directly after checking for "dev->reg_state == NETREG_UNREGISTERING"? Like this?
Possibly a very silly suggestion but perhaps we should set the pointer to NULL for the pcpu case and let it crash?
