Modifying IP&mac address

Hello,

I would like to ask your advise concerning modifying ip address:
I need to modify ip address and ethernet address according to some
hardware input in application. This change can be done in u-boot or
linux.
When I consider where is the best place to set the ip/mac address (
u-boot or linux), I also take into account that I will work with NFS
in debug stage.
Now, as far as I understand, If I will modify the ip/mac in linux
instead of u-boot, it can be a problem when working with NFS, becuase
NFS need constant ip address and ethernet address, right ?
Is it a problem to make this changes in linux if working with NFS or
should it be done in u-boot only ?

Thank you,
Ran

if you store the IP/mac address in u-boot's environment, there are utils to 
update u-boot's environment from under linux.  look under tools/env/.
