The DPAA2 Switch is not capable to handle traffic in a VLAN unaware fashion, thus the previous handling of both the accepted upper devices and the SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING flag was wrong. Fix this by checking if the bridge that we are joining is indeed VLAN aware, if not return an error. Also, the RX VLAN filtering feature is defined as 'on [fixed]' and the .ndo_vlan_rx_add_vid() and .ndo_vlan_rx_kill_vid() callbacks are implemented just by recreating a switchdev_obj_port_vlan object and then calling the same functions used on the switchdev notifier path. In addition, changing the vlan_filtering flag to 0 on a bridge under which a DPAA2 switch interface is present is not supported, thus rejected when SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING is received with such a request. This patch is also adding the use of the switchdev_handle_port_attr_set function so that we can iterate through all the lower devices of the bridge that the notification was received on and actually catch if the user is trying to change the vlan_filtering state. Since on a VLAN filtering change the net_device is the bridge, we also move the dpaa2_switch_port_dev_check call so that we do not return NOTIFY_DONE right away.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
