[PATCH v2 0/1] Make neighbor eviction controllable by userspace

v1 -> v2:

 - It was suggested by Daniel Borkmann to extend the neighbor table settings
   rather than adding IPv4/IPv6 options for ARP/NDISC separately. I agree
   this way is much more concise since there is now only one place where the
   option is checked and defined.
 - Moved documentation/code into the same patch
 - Explained in more detail the test scenario and results

v2 -> v3:

 - Renamed 'skip_perm' to 'nocarrier'. The way this parameter is used
   matches this naming.
 - Changed logic to still flush if 'nocarrier' is false.
