Miller" <davem@...emloft.net> 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. Signed-off-by: Paolo Abeni <pabeni@...hat.com> Signed-off-by: David S.
