Subject: [PATCH 4.9 22/90] ipvlan: egress mcast packets are not exceptional
From: Paolo Abeni <pabeni@...hat.com>
commit cccc200fcaf04cff4342036a72e51d6adf6c98c1 upstream.
Currently, if IPv6 is enabled on top of an ipvlan device in l3
mode, the following warning message:
Dropped {multi|broad}cast of type= [86dd]
is emitted every time that a RS is generated and dmseg is soon
filled with irrelevant messages. Replace pr_warn with pr_debug,
to preserve debuggability, without scaring the sysadmin.
