This patchset requires "net: dsa: add support for switchdev VLAN objects" [1].
Thanks to the switchdev bindings for ports' bridge_getlink, this patchset adds
support for dumping the hardware VLAN Table Unit of Marvell 88E6xxx compatible
switch chips.
It allows "bridge vlan" to query the hardware, and also brings a new debugfs
"vtu" file. A populated VLAN Table Unit can show the following output:
# cat /sys/kernel/debug/dsa0/vtu
VID FID SID P0 P1 P2 P3 P4 P5 P6
550 562 0 x x x u x t x
