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:
