[U-Boot-Users] Ethernet port

Thanks sughosh.

Here in my board I have two Ethernet ports;
So now I have to set two different IP addresses for these ports.

As when the U-Boot prompt comes up we can set the IP address as,

=> set ipaddr
=> set ethaddr aa:bb:cc:ee:ff:gg

So above setting is valid only for single Ethernet port.

My doubt how to set IP address for another Ethernet port or what is the
method to do that?

  Forgot to mention one thing in the previous mail though. It is not
  recommended to configure the mac addresses, using this method. If
  you flash the same u-boot image on multiple boards (which you most
  probably will), the ethernet controllers on all the boards will end
  up having the same mac addresses, which is something you don't
  want. You can configure the mac addresses through the environment
  settings, for each board. Check this,

  I'm not sure what you want to do, but AFAIK, you have a single
  ethernet controller which is active, set by the 'ethact' env
  variable. This is used to send/receive the traffic. So i'm not sure
  why you require multiple ip/gateways and serverip's to be set.
