  12  * Data sheets and programming docs for the DP83840 are available at

  14  *
  15  * The DP83840 is capable of both 10 and 100Mbps ethernet, in both
  16  * half and full duplex mode.  It also supports auto negotiation.
  17  *
  18  * But.... THIS THING IS A PAIN IN THE ASS TO PROGRAM!
  19  * Debugging eeprom burnt code is more fun than programming this chip!
