[PATCH 4.4 14/93] ipvlan: egress mcast packets are not exceptional

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@xxxxxxxxxx>

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.
