This video shows how to use the Linux ethtool and U-Boot MII utilities to 
examine Ethernet link status on Sitara AM-class devices (AM3x, AM43x, and 
AM57x). This is the first debug step when you have determined that there is 
no network activity on an Ethernet link. This training is intended for custom 
board developers who are bringing up their network interface for the first 
time.
