[PATCH v6] Configure the Node a routable IPv6 ULA

[mail at adrianschmutzler.de]

Das Script klappt nicht zu 100 %, ich kann es aber nicht reproduzieren, wenn
nicht klappt.

Sieht dann so aus (VORHER war keine ULA gesetzt):

RTNETLINK answers: File exists
Set ULA address to br-mesh: fd43:5602:29bd:3::60e3:27e7:4d20/64
RTNETLINK answers: File exists
Set ULA route to br-mesh.

Da aber nichts kaputt geht und es meistens klappt, bin ich dafür, erstmal zu
applien.

Grüße

Adrian
