The old - * behaviour broke CDP (Cisco Discovery Protocol). - * o Use dev instead of priv for free_irq() as well as - * request_irq() (oops). - * o Attempt to reset rather than giving up if we get too many - * IRQs. - * o Changed semantics of __orinoco_down() so it can be called - * safely with hw_unavailable set.
