ipv6: Fail with appropriate error code when setting not-applicable sockopt. IPV6_MULTICAST_HOPS, for example, is not valid for stream sockets. Since they are virtually unavailable for stream sockets, we should return ENOPROTOOPT instead of EINVAL. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
