Add support for RX VLAN ctag/stag strip
which may be configured via ethtool.
e.g.
# ethtool -K $DEV rx-vlan-offload on
# ethtool -K $DEV rx-vlan-stag-hw-parse on
Ctag-stripped and stag-stripped cannot be enabled at the same time
because currently the kernel supports only one layer of VLAN stripping.
The NIC supplies VLAN strip information as packet metadata.
The fields of this VLAN metadata are:
* strip flag: 1 for stripped; 0 for unstripped
* tci: VLAN TCI ID
* tpid: 1 for ETH_P_8021AD; 0 for ETH_P_8021Q
Configuration control bits NFP_NET_CFG_CTRL_RXVLAN_V2 and
NFP_NET_CFG_CTRL_RXQINQ are to signal availability of
ctag-strip and stag-strip features of the firmware.

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.
