ipv6: speedup inet6_dump_ifinfo() When handling large number of netdevice, inet6_dump_ifinfo() is very slow because it has O(N^2) complexity. Instead of scanning one single list, we can use the 256 sub lists of the dev_index hash table, and RCU lookups. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
