        !            15: Access to some hardware registers and other things can only be done by one CPU at a time.  
        !            16: An easy way to do this is to make the entire network stack runs with a single lock held, so operations only take place on one core.  
        !            17: This is inefficient, if you ever want to use more than one core, for faster performing cards.
        !            18: 
        !            19: Adapting old drivers to be able to run with the rest of the network stack not having this lock will improve NetBSD networking.  
        !            20: A large number of drivers must be adapted, and some of them can be emulated from virtual machines too, some examples:
