[ Upstream commit 9b0ed890ac2ae233efd8b27d11aee28a19437bb8 ]
Do not report the XDP capability NETDEV_XDP_ACT_XSK_ZEROCOPY as the
bonding driver does not support XDP and AF_XDP in zero-copy mode even
if the real NIC drivers do.
Note that the driver used to report everything as supported before a
device was bonded. Instead of just masking out the zero-copy support
from this, have the driver report that no XDP feature is supported
until a real device is bonded. This seems to be more truthful as it is
the real drivers that decide what XDP features are supported.
Fixes: cb9e6e584d ("bonding: add xdp_features support")

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.
