+ * TODO:
+ * Fix TSO; tx performance is horrible with TSO enabled.
+ * Wake on LAN.
+ * Add more ethtool functions.
+ * Fix abstruse irq enable/disable condition described here:
+ * http://marc.theaimsgroup.com/?l=linux-netdev&m=116398508500553&w=2
+ *
+ * NEEDS TESTING:
+ * VLAN
+ * multicast
+ * promiscuous mode
+ * interrupt coalescing
+ * SMP torture testing

- * Add more ethtool functions.
- * Fix abstruse irq enable/disable condition described here:

- *
- * NEEDS TESTING:

- * SMP torture testing
