Address 0x1a is the WM8904. Address 0x39 is the SIL9022A. I am
not sure what is at address 0x3d and 0x60
14. Networking support via the EMAC 10/100Base-T peripheral can be
added to NSH be selecting the following configuration options.
Remember that only the SAMA5D31 and SAMAD35 support the EMAC
peripheral! This will add several new commands to NSH: ifconfig,
wget, put, get, ping, etc.
