minor nit : This is not necessary anymore
 
	eth_type_trans(skb, dev) does the skb->dev = dev; initialization
in recent kernels.

    [ETH]: Make eth_type_trans set skb->dev like the other *_type_trans

    One less thing for drivers writers to worry about.

This last_rx init is not anymore needed :

    drivers/net: Kill now superfluous ->last_rx stores.

    The generic packet receive code takes care of setting
    netdev->last_rx when necessary, for the sake of the
    bonding ARP monitor.

    Drivers need not do it any more.

    Some cases had to be skipped over because the drivers
    were making use of the ->last_rx value themselves.

pkt_len is an "unsigned int", so please use %u

Please add a const qualifier to this.



struct dnet {

+	spinlock_t			lock;
+	struct platform_device	*pdev;
+	struct net_device		*dev;
+	struct net_device_stats	stats;
+	struct dnet_stats		hw_stats;
+	unsigned int			capabilities; /* read from FPGA */
+	struct napi_struct		napi;


Are you sure you need a "struct net_device_stats stats;" in "struct dnet" ?
One is already included in "struct net_device", you probably can use it.

Thank you
