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.

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

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

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

etc...
