Network stack unstable after arp flapping

[K. Macy]

I don't think it was properly tested when it was enabled for IPv6.
Given that I have been absentee it really should not be in the default
kernel or at least the sysctl should be off. Sorry for the
inconvenience. Additionally, you don't need to rebuild you can just
disable the sysctl.
