[ECOS] changing MAC address

I was able to make 82545GM ethernet functional in Redboot, I am now able 
to ping or load file via tftp.
Now I want to make it possible to set MAC address from Redboot, because 
in the initial state of hardware - MAC address is filled with 00's.

What is the best way to change MAC address of ethernet controller from 
the command line of Redboot?

Intel 82544 driver contains function "set_mac_address" and it is used in 
ioctl handler, but:
1) it doesn't write to EEPROM, so it changes MAC address only for a 
while - am I right?
2) MAC address is read during the network initialization in RedBoot, 
even if I change it from command line, I will need to ask for BOOTP 
again, right?
