        !            16: Traditionally, the kernel code had been protected by a single, global lock.
        !            17: This lock ensured that, on a multiprocessor system, two different threads
        !            18: of execution did not access the kernel concurrently and thus simplified the
        !            19: internal design of the kernel.  However, such design does not scale to
        !            20: multiprocessor machines because, effectively, the kernel is restricted to
        !            21: run on a single processor at any given time.
        !            22: 
        !            23: The NetBSD kernel has been modified to use fine grained locks in many of
        !            24: its different subsystems, achieving good performance on today's
        !            25: multiprocessor machines.  Unfotunately, these changes have not yet been
        !            26: applied to the networking code, which remains protected by the single lock.
        !            27: 
        !            28: The aim of this project is to remove the single lock surrounding the
        !            29: networking code in the kernel, allowing such code to execute more
        !            30: efficiently in multiprocessor machines.

        !            33: performance of the networking subsystem in current machines is critical to
