Subject: [PATCH net-next v2 1/2] mcast: define and use MRT[6]_MAX in ip[6]_mroute_opt()
This will ease further addition of new MRT[6]_* values and avoid to update
in6.h each time.
Note that we reduce the maximum value from 210 to 209, but 210 does not match
any known value in ip[6]_mroute_setsockopt().
