Log Message:
RA flood mitigation via a limit on accepted routes:
- introduce a limit for the routes accepted via IPv6 Router Advertisement:
  a common 2 interface client will have 6, the default limit is 100 and
  can be adjusted via sysctl
- report the current number of routes installed via RA via sysctl
- count discarded route additions. Note that one RA message is two routes.
  This is at present only across all interfaces even though per-interface
  would be more useful, since the per-interface structure complies to RFC2466
- bump kernel version due to the previous change
- adjust netstat to use the new value (with netstat -p icmp6)
