  * This driver is written and optimized for Intel Xscale technology.

  * SETUP NOTES:
- * By default, this driver uses predefined MAC addresses.
- * These are set in global var 'default_mac_addr' in this file.
- * If required, these can be changed at run-time using
- * the 'ifconfig' tool.
+ * By default, this driver uses MAC addresses from maclist, if
+ * these are not available the kernel api to randomly generate
+ * a locally assigned MAC address is used.  The MAC can be
+ * overridden with ifconfig if absolutely necessary.
  *
  * Example - to set ixp0 MAC address to 00:02:B3:66:88:AA, 
  * run ifconfig with the following arguments:
