    if: Per-cpu ifnet/ifaddr statistics, step 3/3
    
    Make ifnet stats per-cpu.  The per-cpu stats are stored in cache aligned
    ifdata_pcpu struct.
    
    - if_mib code is adjusted, so callers of the IFMIB_IFDATA sysctl will not
      aware of the ifnet per-cpu stats, e.g. systat -if
    - User space programs that directly access ifnet.if_data are modified to
      aware of the new location of the ifnet stats, e.g. netstat -in
