commit 9e3d9ae52b5657399a7b61258cc7482434a911bb upstream. It is possible to trigger these VTU violation messages very easily, it's only necessary to send packets with an unknown VLAN ID to a port that belongs to a VLAN-aware bridge. Do a similar thing as for ATU violation messages, and hide them in the kernel's trace buffer. New usage model: $ trace-cmd list | grep mv88e6xxx mv88e6xxx mv88e6xxx:mv88e6xxx_vtu_miss_violation mv88e6xxx:mv88e6xxx_vtu_member_violation $ trace-cmd report Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Saeed Mahameed <saeed@kernel.org> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org> Cc: Fabio Estevam <festevam@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
