   4 Subject: [PATCH 551/703] phy: bcm54213pe: configure the LED outputs to be more
   5  user-friendly
   6
   7 The default state was both LEDs indicating link speed.
   8
   9 Change the default configuration to
  10 - Amber: 1000/100 link speed indication
  11 - Green: link present + activity indication
