you just want:
         printk(KERN_INFO "%pM", netdev->dev_addr);

or better yet, convert to dev_printk

or perhaps better still convert to netdev_info

My message logging order preference:

if there's a netif_msg_<type> and a struct net_device
	netif_<level>		(struct private *, netif_msg_<type>,
				 struct net_device *, fmt, args...)
if there's a struct net_device
	netdev_<level>		(struct net_device *, fmt, args...)
if there's a struct device
	dev_<level>		(struct device *, fmt, args...)
otherwise
	pr_<level>		(fmt, args...)
