Merge branch 'dsa-port-vlan-dump'

Vivien Didelot says:

====================
net: dsa: add port VLAN dump operation

The VLAN GetNext approach is specific to some switches and thus hard to
implement for others. This patchset replaces it with a simpler port VLAN dump
operation, similar to the corresponding FDB operation.

The mv88e6xxx driver is the only one currently affected by the change.
The documentation is updated accordingly.

Note: this patchset uses http://www.spinics.net/lists/kernel/msg2186705.html

queried for the given switch port
- port_pvid_set: bridge layer function invoked when a Port-based VLAN ID needs
to be configured on the given switch port

(tagged or untagged) for the given switch port
- port_vlan_del: bridge layer function invoked when a VLAN is removed from the
given switch port
- vlan_getnext: bridge layer function invoked to query the next configured VLAN
in the switch, i.e. returns the bitmaps of members and untagged ports
- port_vlan_dump: bridge layer function invoked with a switchdev callback
function that the driver has to call for each VLAN the given port is a member
of. A switchdev object is used to carry the VID and bridge flags.
