Hello.
If net.ipv6.conf.default.forwarding is !0 when bringing up the interface,
we failed to join all routers multicast address, while we join/leave if we
enable/disable net.ipv6.conf.ethX.forwarding later.
This is inconsistent because we assume that we join all routers multicast
if and only if net.ipv6.conf.ethX.forwarding is !0.
So, make sure to join all routers multicast address if forwarding is enabled
on the interface.
