    netgraph/ng_bridge: become SMP aware
    
    The node ng_bridge underwent a lot of changes in the last few months.
    All those steps were necessary to distinguish between structure
    modifying and read-only data transport paths.  Now it's done, the node
    can perform frame forwarding on multiple cores in parallel.
