ipmr/ip6mr: advertise mfc stats via rtnetlink
These statistics can be checked only via /proc/net/ip_mr_cache or SIOCGETSGCNT[_IN6] and thus only for the table RT_TABLE_DEFAULT. Advertising them via rtnetlink allows to get statistics for all cache entries, whatever the table is. Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.
