No, you can enable per interface SLAAC on 2.6.32 as well. It's just a
little more convoluted than setting accept_ra=2. I have added this to a
# need to disable forwarding to receive RAs
sysctl -w net.ipv6.conf.$PPP_IFACE.forwarding=0
Note that this only enables RA acceptance on the interface. It does
*not* disable forwarding of IPv6 packets. That's controlled by the
global net.ipv6.conf.all.forwarding variable, and ip6tables rules.
It's all a bit weird, which I assume is why the accept_ra=2 was
