[U-Boot] How to disable MAC address for usb_ether

[Xuebing Wang]

Hi,

My board has one Ethernet, one USB Host and one USB Slave.

Command bdinfo shows below:

eth0name    = cpsw
ethaddr     = 90:59:af:54:1a:28
eth1name    = usb_ether
eth1addr    = 90:59:af:54:1a:2a
current eth = cpsw

Would you please teach me how to disable usb_ether MAC address, thus 
bdinfo will show "eth1addr    = (not set)"?

Thanks a lot.
