netdevice: Add offload statistics ndo
Add a new ndo to return statistics for offloaded operation. Since there can be many different offloaded operation with many stats types, the ndo gets an attribute id by which it knows which stats are wanted. The ndo also gets a void pointer to be cast according to the attribute id.
