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 ---------------------------------------------------------------- 6250 | 0.23 s | 0.13 s | 0.11 s 12500 | 0.62 s | 0.28 s | 0.22 s 25000 | 2.91 s | 0.57 s | 0.46 s 50000 | 11.37 s | 1.21 s | 0.94 s 128000 | 86.78 s | 3.05 s | 2.54 s Signed-off-by: Mihai Maruseac <mmaruseac@ixiacom.com> Cc: Daniel Baluta <dbaluta@ixiacom.com> Signed-off-by: David S.
