net: dsa: mv88e6xxx: replace VTU violation prints with trace points
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
