This RFC is based on v4.1-rc3.

It is meant to get a glance to the commits responsible to implement the
necessary NDOs between DSA and the Marvell 88E6352 switch driver.

With this support, I am able to create VLANs with (un)tagged ports, setting
their default VID, from a bridge.

To create a bridge containing all switch ports, with a VLAN ID 400, swp2 and
swp3 untagged (pvid), and swp4 tagged, the userspace commands look like this:

     ip link add name br0 type bridge
     [...]
     ip link set dev swp2 up master br0
     [...]
     bridge vlan add vid 400 pvid untagged dev swp2
     bridge vlan add vid 400 pvid untagged dev swp3
     bridge vlan add vid 400 dev swp4
     [...]
     ip link add link br0 name br0.400 type vlan id 400
     [...]
     bridge vlan add dev br0 vid 400 self

The code is currently being rebased to the latest net-next/master.

Seems like the way to go now is through switchdev attr getter/setter...

Indeed, for dsa_slave you should be able to port this to switchdev and
set your ndo_bridge_setlink/dellink handlers to
switchdev_port_bridge_setlink/dellink.  (And also implement the
switchdev ops for vlans).

If you use switchdev_port_bridge_setlink/dellink, you shouldn't need
to implement ndo_vlan_rx_add_vid/ndo_vlan_rx_kill_vid at all.  The

Those functions are called from net/8021q/vlan_core.c if a vlan is configured
on or removed from an interface. Does that result in a call to setlink/dellink
as well, even if a switch port is not a member of a bridge group ?
