Subject: arm: xea: Provide function to set L2 switch 'local-mac-address' property
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-logo.png?a=commitdiff_plain;h=bcd7f8941420734a40147faf887fe7c55faca4ca;p=u-boot.git

arm: xea: Provide function to set L2 switch 'local-mac-address' property

The 'local-mac-address' property needs to be adjusted to the MAC address
value stored in U-Boot's 'ethaddr' env variable.
