Subject: [PATCH 5/5] ipvs: log additional sync daemon parameters

Add new multicast parameters to log messages when sync daemons start.

Commits <e4ff67513096> ("ipvs: add sync_maxlen parameter for the sync
daemon") and <d33288172e72> ("ipvs: add more mcast parameters for the
sync daemon") added additional multicast parameters, but didn't add
them to the log messages when the sync daemons started.
