++ * a simple driver to remember ethernet MAC values
++ *
++ * Some Ethernet hardware implementations have no built-in
++ * storage for allocated MAC values - an example is the Intel
++ * IXP420 chip which has support for Ethernet but no defined
++ * way of storing allocated MAC values.  With such hardware
++ * different board level implementations store the allocated
++ * MAC (or MACs) in different ways.  Rather than put board
++ * level code into a specific Ethernet driver this driver
++ * provides a generally accessible repository for the MACs
++ * which can be written by board level code and read by the
++ * driver.
++ *
++ * The implementation also allows user level programs to
++ * access the MAC information in /proc/net/maclist.  This is
++ * useful as it allows user space code to use the MAC if it
++ * is not used by a built-in driver.
