Currently we will already fill ethaddr with a fixed unique address based on the SoCs serial (from the sid) to make sure that boards which use the integrated emac / gmac get a fixed mac rather then a random one.
On some boards (observed on 2 tablets using sdio rtl8703as wifi chips) the wifi does not come with a fixed mac either, so also set eth1addr, so that dts files can set an ethernet1 alias to get mac-address and local-mac-address filled for dt nodes describing the wifi controller.
