[PATCH v4] gateway.d: Add scripts for network configuration

[robert]

Hi Fabian,

mein sed Hinweis war nicht getestet. Sorry.

Man erwischt zwar alle ethxx.xxx aber nicht am Zeilenende. Und ein
veth.0 wird zerhackt.

Musste das auch erst mal ausprobieren. Ein

sed 's/\beth[^ ]* *//g'

tut was es soll. Probiere es bitte auch noch mal aus.

Kannst du dann beim Applien anpassen.
