[PATCH net-next] ipvlan: egress mcast packets are not exceptional

[PATCH net-next] ipvlan: egress mcast packets are not exceptional

[Paolo Abeni]

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.
