[OpenWrt-Devel] [PATCH] lantiq, xrx200-net: add new 'id' devicetree property

[Martin Schiller]

This patch adds the new 'id' devicetree property, which makes it possible to
renumber the physical mac ports.

This change has only cosmetical reasons (e.g. appearance in swconfig,
kernel messages on link change).
