From fc4eba58b4c1462ff3d6247b66fb47d6928db6d2 Mon Sep 17 00:00:00 2001 From: Hannes Frederic Sowa Date: Wed, 14 Aug 2013 01:03:46 +0200 Subject: ipv6: make unsolicited report intervals configurable for mld Commit cab70040dfd95ee32144f02fade64f0cb94f31a0 ("net: igmp: Reduce Unsolicited report interval to 1s when using IGMPv3") and 2690048c01f32bf45d1c1e1ab3079bc10ad2aea7 ("net: igmp: Allow user-space configuration of igmp unsolicited report interval") by William Manley made igmp unsolicited report intervals configurable per interface and corrected the interval of unsolicited igmpv3 report messages resendings to 1s. Same needs to be done for IPv6: MLDv1 (RFC2710 7.10.): 10 seconds MLDv2 (RFC3810 9.11.): 1 second Both intervals are configurable via new procfs knobs mldv1_unsolicited_report_interval and mldv2_unsolicited_report_interval. (also added .force_mld_version to ipv6_devconf_dflt to bring structs in line without semantic changes) v2: a) Joined documentation update for IPv4 and IPv6 MLD/IGMP unsolicited_report_interval procfs knobs. b) incorporate stylistic feedback from William Manley v3: a) add new DEVCONF_* values to the end of the enum (thanks to David Miller) Cc: Cong Wang Cc: William Manley Cc: Benjamin LaHaise Cc: YOSHIFUJI Hideaki Signed-off-by: Hannes Frederic Sowa Signed-off-by: David S.
