In order for the driver to support 802.1ad VLAN filtering and offloads, it needs to advertise those VLAN features and also support modifying those VLAN features, so make the necessary changes to ice_set_netdev_features(). By default, enable CTAG insertion/stripping and CTAG filtering for both Single and Double VLAN Modes (SVM/DVM). Also, in DVM, enable STAG filtering by default. This is done by setting the feature bits in netdev->features. Also, in DVM, support toggling of STAG insertion/stripping, but don't enable them by default. This is done by setting the feature bits in netdev->hw_features. Since 802.1ad VLAN filtering and offloads are only supported in DVM, make sure they are not enabled by default and that they cannot be enabled during runtime, when the device is in SVM. Add an implementation for the ndo_fix_features() callback. This is needed since the hardware cannot support multiple VLAN ethertypes for VLAN insertion/stripping simultaneously and all supported VLAN filtering must either be enabled or disabled together. Disable inner VLAN stripping by default when DVM is enabled. If a VSI supports stripping the inner VLAN in DVM, then it will have to configure that during runtime. For example if a VF is configured in a port VLAN while DVM is enabled it will be allowed to offload inner VLANs.

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.
