ipv6/addrconf: speedup /proc/net/if_inet6 filling
This ensures a linear behaviour when filling /proc/net/if_inet6 thus making
ifconfig run really fast on IPv6 only addresses. In fact, with this patch and
the IPv4 one sent a while ago, ifconfig will run in linear time regardless of
address type.
IPv4 related patch: f04565ddf52e401880f8ba51de0dff8ba51c99fd
dev: use name hash for dev_seq_ops
...
Some statistics (running ifconfig > /dev/null on a different setup):
iface count / IPv6 no-patch time / IPv6 patched time / IPv4 time
