Subject: wifi-scripts: add macaddr_base wifi-device option
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=00860e485b2ef82c1fafc8e011f3a8965e317bca;p=openwrt%2Fstaging%2Fxback.git

wifi-scripts: add macaddr_base wifi-device option

This can be used to configure the base mac address from which all
interface mac addresses are derived
