    BTW. Not compiling in DEVICE_POLLING has any advantages except few bytes
    smaller kernel?
    I wonder if we could drop yet another kernel option and just set
    kern.poll.enable to 0 by default.
    If adding DEVICE_POLLING to the kernel doesn't cost additional locking, etc.
    in network data flow paths (which could lead to performance impact in some
    specific environments) can we just compile the code in always?
