Allow support for S-Tag + C-Tag VLAN traffic by disabling pruning when there are no 0x8100 VLAN interfaces currently created on top of the PF. When an 0x8100 VLAN interface is configured, enable pruning and only support single and double C-Tag VLAN traffic. If all of the 0x8100 interfaces that were created on top of the PF are removed via ethtool -K <iface> rx-vlan-filter off or via ip tools, then disable pruning and allow S-Tag + C-Tag traffic again. Add VLAN 0 filter by default for the PF. This is because a bridge sets the default_pvid to 1, sends the request down to ice_vlan_rx_add_vid(), and we never get the request to add VLAN 0 via the 8021q module which causes all untagged traffic to be dropped.

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.
