    network - Fix MP races in GIF
    
    * GIF used a single route cache across all CPUs causing races.  In addition
      GIF did not clean out the cache when destroying an interface or changing
      the address family.
    
    * Change the single route cache entry to an array[SMP_MAXCPU] and also
      separate out the inet4 and inet6 route cache entries.
