      How reproducible is this bug?:

      Always

      Steps to reproduce

      1. Try to run xdp-trafficgen on mlx5 card on kernel 

        6.12.0-211.el10.x86_64

        [++ xdp-trafficgen udp bond0 -m 00:de:ad:de:ad:01 -M 00:de:ad:00:00:01 -a 2000::1 -A 2000::2 -t 4
        Interface bond0 does not support sending packets via XDP.  

      Expected results:

      xdp-trafficgen used to run on bond interface without explicit xdp dispatcher loaded in nic unlike intel drivers. 

      Actual results:

      https://beaker.engineering.redhat.com/jobs/12350199

      ++ xdp-trafficgen udp bond0 -m 00:de:ad:de:ad:01 -M 00:de:ad:00:00:01 -a 2000::1 -A 2000::2 -t 4
      Interface bond0 does not support sending packets via XDP.
