Subject: mediatek: bpi-r4: store random MAC addresses for the BPi-R4
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5709254690cb4181c2c9aed7c0569b7bafea6118;p=openwrt%2Fstaging%2Fpepe2k.git

mediatek: bpi-r4: store random MAC addresses for the BPi-R4

Despite coming with multiple I2C EEPROMs supposedly dedicated for that
purpose, the BPi-R4 does not seem to have factory assigned MAC addresses.
Hence, just like for all other BPi boards, store a randomly generated
MAC address on first boot and derive WAN and Wi-Fi MAC addresses from
that as well. Not perfect, but better than random on every boot.
