VFs by default are able to see all tagged traffic regardless of trust and VLAN filters. Based on legacy devices (i.e. ixgbe, i40e), customers expect VFs to receive all VLAN tagged traffic with a matching destination MAC. Add an ethtool private flag 'vf-vlan-pruning' and set the default to off so VFs will receive all VLAN traffic directed towards them. When the flag is turned on, VF will only be able to receive untagged traffic or traffic with VLAN tags it has created interfaces for. Also, the flag cannot be changed while any VFs are allocated. This was done to simplify the implementation. So, if this flag is needed, then the PF admin must enable it. If the user tries to enable the flag while VFs are active, then print an unsupported message with the vf-vlan-pruning flag included. In case multiple flags were specified, this makes it clear to the user which flag failed.

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.
