Subject: Fix DM9000 MAC address handling
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0775437293a6963cb21244dfae6978cbf67c6bfe;p=u-boot.git

Fix DM9000 MAC address handling

Proper behavior is to pull MAC address from NVRAM in the initialization() an
stuff it in dev->address, then program the device from dev->address in
the init() function.
