[ Upstream commit164844135a] Currently ksz8_port_vlan_filtering() sets or clears the VLAN Enable hardware flag. That controls discarding of packets with a VID that has not been enabled for any port on the switch. Since it is a global flag, set the dsa_switch::vlan_filtering_is_global flag so that the DSA core understands this can't be controlled per port. When VLAN filtering is enabled, the switch should also discard packets with a VID that's not enabled on the ingress port. Set or clear each external port's VLAN Ingress Filter flag in ksz8_port_vlan_filtering() to make that happen.

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.
