Per the DT spec, 'local-mac-address' is used to specify MAC address
that was assigned to the network device, while 'mac-address' is used
to specify the MAC address that was last used by the boot program,
and shall be used only if the value differs from 'local-mac-address'
property value.

U-Boot expects this alias to be in place in order to fix up the mac
address of the ethernet node.
Note on the Icicle Kit board, currently only emac1 is enabled so it
becomes the 'ethernet0'.

Ping?
It looks like these dts patches are still not applied...

Is there any point in providing an all-zeros MAC address at all?
Can't it just be removed?

BTW, is Ethernet working in Linux for you?
IP-Config is always timing out for me.
Thanks!
