The smc911x_halt gets called after completion of network opration and resets the chip. When there is no SROM attached to the SMSC, MAC address gets reset as well. Add CONFIG_SMC911X_KEEP_MAC option to allow boards with no SROM instruct the SMSC driver to keep mac address after the reset
the mac already has proper storage -- the environment. please read doc/REAdME.enetaddr. so i dont thinkt his option should be added.
If you have no network activity in U-Boot the mac address never gets from the environment to the SMSC chip. So, when the kernel boots there's no mac address neither in the chip registers nor in (absent) SROM.
this is correct u-boot behavior. please read the faq. http://www.denx.de/wiki/view/DULG/EthernetDoesNotWorkInLinux -mike
