    Wow guys, this is great stuff, thanks!

    Here's what I've discovered so far and again,
    correct me if I'm wrong.

    In strategy, I need to protect from my callout
    and netisr running. In my netisr, I need to
    protect from my callout running. In my callout,
    I need to protect from my netisr running.

    It looks like I can use splnet() everywhere *except*
    where I'm pulling mbufs off of the mbuf queue in the
    netisr routine. There I'll have to use splimp() to
    keep from banging heads with the hardware.

    I think this is the optimum spl-ing as it will allow
    the network hardware to keep queueing up packets as I
    process them. Comments?

    Sam
