VLAN pruning is not valid when VLAN 0 is not active. If VLAN pruning is enabled and VLAN 0 is not active (8021q driver not loaded) then normal, non-VLAN, traffic will not pass. TX/RX VLAN pruning is enabled when the VLAN 0 is added to the active_vlan bitmap and it is disabled when VLAN 0 is removed from the active_vlan bitmap. So, only enable VLAN pruning when VLAN 0 is active. Setting RX VLAN pruning causes the switch to drop received VLAN packets when there are no matching VLAN ids in the associated VSI's switch filters. Setting TX pruning makes it so the switch will not send out any packets with VLAN tags that don't match the associated VSI's switch filters. With this patch, if the VF or PF tries to send a VLAN tagged packet with a VLAN tag that it does not have a pruning rule for it will trigger an MDD event. For example, if PF0 has VLAN10 and VLAN11 interfaces and scapy is used to send a packet with VLAN8 then the MDD is triggered. Also make ice_vsi_kill_vlan return a value which the caller can check before updating VLAN related data structures (counts, pruning bits, etc.).

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
