Heng Qi 3ef2a16a1d virtio_net: fixing XDP for fully checksummed packets handling 
[ Upstream commit 703eec1b24 ]

The XDP program can't correctly handle partially checksummed
packets, but works fine with fully checksummed packets. If the
device has already validated fully checksummed packets, then
the driver doesn't need to re-validate them, saving CPU resources.

Additionally, the driver does not drop all partially checksummed
packets when VIRTIO_NET_F_GUEST_CSUM is not negotiated. This is
not a bug, as the driver has always done this.

Fixes: 436c9453a1 ("virtio-net: keep vnet header zeroed after processing XDP")

README 

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.
