[PATCH 0/3] net: dsa: mv88e6xxx: dump hardware VLANs

[Vivien Didelot]

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
    1000 1012 0    x  x  t  x  x  t  x
    1200 1212 0    x  x  t  x  t  t  x

    # bridge vlan
