[arch-projects] [netctl][PATCH] Disable IPv6 on IP6=no

[Jouke Witteveen]

---
It was proposed to disable IPv6 entirely in case of "IP6=no".
Currently we only disable processing of router advertisements.
This looks OK to me, but I would really like to get some feedback on
this one, as I cannot extensively test the consequences.
