    (I know this is a somewhat old message).  I think work could be started
    on ALTQ and PF, though it is almost certain that both Jeff and I will have
    to mess with it later on when we start to remove the BGL from the network 
    stack.

    The only 'correct' way to make the packet filters MP safe is to partition
    them across cpus, matching the filter entry with the IP demux hash, and
    then replicating those filter entries that are not sufficiently
    unique to fall into a single demux hash cpu category (for static entries),
    or forcing the entries to be handled by a particular cpu (for dynamic
    entries).  

    It's a headache either way but I don't see it as being a showstopper
    any more... it's just something we will have to do after the fact.

    I would rather have PF and ALTQ in the system and then remove
    the other filters (e.g. the old IPFW filter), and implement any
    lost functionality in PF itself.  Then we would only have to deal
    with PF and ALTQ for the MP work.
