Changes from v3:
- added comment noting eth1 is connected to switch as well
Changes from v2:
- added linksys to filename
- added make rule
Changes from v1:
- changed console to stdout-path
- removed unnecesarry @0 from dsa node, and fixed dsa/switch node
- fixed partitions according to the official docs
- prefer node labels rather than full hierarchy where possible
