[Bug 1260241] [NEW] IPv6 Forwarding node does not autoconf

[Sargun Dhillon]

Public bug reported:

If, in /etc/network/interfaces, you configure a network interface to be
IPv6 autoconfigured, it sets accept_ra to 1. If, you also enable IPv6
forwarding on your machine, the kernel doesn't actually autoconf if
accept_ra is only set to 1, you must set it to 2. The details are
outlined here about how the kernel changed behaviour:

advertisements-and-forwarding/

Ideally, ifupdown would either enable you to manually override accept_ra
(and set it to 2), or always set it to 2, as opposed to 1.
