Non-uplink representor port does not support XDP. The patch clears
the xdp feature by checking the net_device_ops.ndo_bpf is set or not.
Verify using the netlink tool:
$ tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml --dump dev-get
Representor netdev before the patch:
{'ifindex': 8,
'xdp-features': {'basic',
'ndo-xmit',
'ndo-xmit-sg',
'redirect',
'rx-sg',
'xsk-zerocopy'},
'xdp-rx-metadata-features': set(),
'xdp-zc-max-segs': 1,
'xsk-features': set()},
With the patch:
{'ifindex': 8,
'xdp-features': set(),
'xdp-rx-metadata-features': set(),
'xsk-features': set()},
Fixes: 4d5ab0ad96 ("net/mlx5e: take into account device reconfiguration for xdp_features flag")

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 reStructuredText 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.
