Dear Jayakumar A,

This information is 4 years old and obsolete.

If you are talk about "retrieve from a file" you probably mean under
Linux?  That should be trivial to implement.

In U-Boot, we use the environment to store MAC addresses.

This is all Linux stuff and off topic here.  Also, LTIB is Freesale's
code, so please ask Freescale support about it.

It is totally unclear to me what you are actually asking 0 it seems
you confuse MAC and IP addresses at a pretty much fundamental level.
In any case, you appear to refer to Linux configuration, which is off
topic here.
