    if: Add compat mode for ifnet stats so that 3rd party apps can work
    
    If ifnet stats compat mode is enabled, the per-CPU ifnet stats will
    be collected into ifnet old stats location in the if slow timer.
    
    Sysctl node net.link.stats_compat is used to control whether the
    ifnet stats compat mode should be enabled or not; it is _not_ enabled
    by default.
