From 5353102f2d7e2f61cca4014aacfa3ac9a71aaeea Mon Sep 17 00:00:00 2001

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