VAR-SOM-AM43 - On Carrier Gbit Ethernet ETH1

This Second ethenet interface (phy on carrier board) is available only if the VAR-SOM-AM43 SOM without a WiFi module.
In Uboot an autodetect mechanism will detect the type of module used and select the proper .dtb accordingly.
For a module with WiFi 'var-som-am43.dtb' is selected, for a module without WiFi 'var-som-am43-eth1.dtb' is selected.

Please follow the instructions below to activate the ETH1 device and acquire IP for testing.

On Target:

$ ifconfig eth0 down
$ ifconfig eth1 up
$ udhcpc -i eth1
$ ifconfig 
$ iperf -s -u

On Host:

$ iperf -c 192.168.1.82 -u -b450M
