Add support for the XGMAC 10Gb ethernet device in the Calxeda Highbank

Hi Rob, just trivia:

Most of the logging dev_<level> messages
should be netdev_<level>

Adding #define pr_fmt KBUILD_MODNAME ": " fmt
before any #include would be useful to prefix
the module name to pr_<level> output.

+static int desc_get_tx_status(struct xgmac_extra_stats *x,
+			      struct xgmac_dma_desc *p, void __iomem *ioaddr)
+{

[]

+	if (status & TXDESC_JABBER_TIMEOUT) {
+		pr_debug("\tjabber_timeout error\n");
+		x->tx_jabber++;
+	}

Adding pr_fmt, the output would become:
calxeda_xgmac: 	jabber_timeout error

[]

+static void xgmac_rx_refill(struct xgmac_priv *priv)

+		dev_dbg(priv->device, "rx ring: head %d, tail %d\n",
+			priv->rx_head, priv->rx_tail);

	netdev_dbg(priv->dev, "rx ring: head %d, tail %d\n",
		   etc...)
[]

+static int xgmac_open(struct net_device *dev)
+{

[]

+	if (!is_valid_ether_addr(dev->dev_addr)) {
+		random_ether_addr(dev->dev_addr);
+		dev_dbg(priv->device, "generated random MAC address %pM\n",
+			dev->dev_addr);

		netdev_dbg(dev, "generated random MAC address %pM\n",
			   dev->dev_addr);

etc...

cheers, Joe
