net/ipv6: Fix misuse of proc_dointvec "flowlabel_reflect"
/proc/sys/net/ipv6/flowlabel_reflect assumes written value to be in the range of 0 to 3. Use proc_dointvec_minmax instead of proc_dointvec. Fixes: 323a53c41292 ("ipv6: tcp: enable flowlabel reflection in some RST packets") Signed-off-by: Eiichi Tsukata <devel@etsukata.com> Signed-off-by: David S. Miller <davem@davemloft.net>
