Isn't the "from" the "source network" in /proc/net/ipv6_route? (as
described in <http://www.tldp.org/HOWTO/Linux+IPv6-HOWTO/proc-net.html>)

I have a node with multiple Ethernet interfaces, each of which connected
to a different network where IPv6 Router Advertisements are received...
and the "source network" is set to all-zeros in all cases.

Thanks!
