 extern void usbnet_get_drvinfo(struct net_device *, struct ethtool_drvinfo *);
+extern int usbnet_mii_ioctl(struct net_device *net, struct ifreq *rq, int cmd);

Do we still need to populate 'extern'? Can we get rid of this redundancy?

 extern int usbnet_nway_reset(struct net_device *net);

 extern int usbnet_manage_power(struct usbnet *, int);
