net/mlx5e: clear xdp features on non-uplink representors
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: 4d5ab0ad964d ("net/mlx5e: take into account device reconfiguration for xdp_features flag")
