From adfa85e45dac616ff4f8bfceff1621ccafc0b1ff Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Tue, 4 Dec 2012 01:13:37 +0000 Subject: 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 Signed-off-by: David S.
