Subject[PATCH 4.14 35/99] ipvlan: egress mcast packets are not exceptional
Date
From: Paolo Abeni <pabeni@redhat.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.
