Subject: Xilinx: ARM: net: Program the MAC address to hardware on boot
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8b6c84379bd3888a2ebdcf0e52640427df0e901e;p=thirdparty%2Fu-boot.git

Xilinx: ARM: net: Program the MAC address to hardware on boot

This will allow Linux to not make up a new MAC on each boot and never
keep the same IP address from boot to boot.
