Kernel tries to be helpful and attach the XDP program in generic mode if the driver has no BPF ndo at all. Since the xdp.py tests all have "native" in their names this can be quite confusing. Force native / "drv" attachment. Note that netdevsim re-uses the generic handler as its "native" handler, so we'll maintain the test coverage of the generic mode that way. No need to test both explicitly, I reckon.
